FYI,
                
                I did a relatively quick analysis to determine which
                  packages actually contain incubating components.  This
                  involves is looking in each package zip for plugins
                  with 0.* versions, which is complicated by the fact
                  that many non-incubating projects are nevertheless
                  shipping 0.* versions of bundles.
                So I make the following assumptions about plugins
                  that look to be incubating, based on the version
                  number, but apparently are not incubating:
                
                
                  - exclude all Orbit bundles, i.e., all bundles not
                    of the form org.eclipse.*
- exclude all org.eclipse.e4.*
 
- exclude  org.eclipse.m2e.workspace.cli
- exclude all org.eclipse.passage.* which claims to
                    be graduated from incubation
- exclude org.eclipse.tips.*
- exclude
                    org.eclipse.tracecompass.analysis.counters.ui
- exclude org.eclipse.wst.jsdt.chromium.*
 
Other than the Orbit bundles, all these org.eclipse.*
                  bundles with 0.* version numbers are in kind of a
                  questionable state, in my opinion, but let's ignore
                  that and exclude them.
                
                This leaves only bundles from the following projects,
                  all of which are actually marked as incubating in the
                  portal:
                
                https://projects.eclipse.org/projects/technology.tm4e
                  https://projects.eclipse.org/projects/tools.wildwebdeveloper
                  https://projects.eclipse.org/projects/technology.lsp4e
                  https://projects.eclipse.org/projects/technology.lsp4j
                  https://projects.eclipse.org/projects/science.swtchartk
                  https://projects.eclipse.org/projects/tools.corrosion
                Here's the command that I ran in a folder with all
                  the *.zips downloaded from
                  https://download.eclipse.org/technology/epp/downloads/release/2020-03/RC2a/
                
                $for i in *.zip; do echo $i; unzip -l $i
                  "eclipse/plugins/*" | grep "_0\\." | sed
                  "1,\$s/.*eclipse\/plugins\//  /g" | grep
                  "org\\.eclipse\\." | grep -v "org\\.eclipse\\.e4\\..*"
                  | grep -v "org\\.eclipse\\.wst\\.jsdt\\.chromium.*" |
                  grep -v "org\\.eclipse\\.passage\\..*" | grep -v
                  "org\\.eclipse\\.tips\\..*" | grep -v
                  "org\\.eclipse\\.tracecompass\\..*" | grep -v
                  "org\\.eclipse\\.m2e\\.workspace\\.cli.*" | sort; done
                This prints out the following summary, where the
                  packages in bold are packages not marked as incubating
                  but that actually do contain incubating components:

                It seems to me that three of the package maintainers
                  (committers, dsl, and parallel/science) are not
                  actively paying attention to Jonah's previous request
                  for maintainers to maintain the incubation status of
                  their package.
                I don't know if it's too late now.  Certainly the web
                  page is generated later from the packageName of the
                  packageMetaData, but the artifact names use the name
                  attribute of the product element and the artifacts
                  with their final names already exist now.
