Cen,
It's hard to get a particular statement or desire from your many points.
I get a "Jakarta EE bad, Microprofile cool" sentiment, but that is not new.
Without Java EE there would be neither Spring nor Microprofile.
MP is a lot like Spring, but it is still in a very early stage, comparable to Spring 1.2 rather than 2.0, especially when you look at true adoption or answers to surveys.
Plus Jakarta EE 8 is 1 or sometimes 2 steps ahead of Microprofile specs that have not been upgraded to use Java EE 8 yet. It's a "Dependency Hell" because some need CDI 1.2, others already require 2.x
A large number of Spring projects already uses the new Jakarta EE specs. ;-D
You discovered that EclipseLink has more than Bugzilla and the more recent important ones should be there. Bugzilla has many, but Hibernate ORM alone got 2861 open issues in its JIRA, so does that mean you consider both abandonware? ;-)
The "incremental vs. Big bang" discussion was about refactoring from javax to jakarta namespaces and not how many new specs Jakarta EE 9, 10 or 11 might include. For 8 everything was put in a new Maven Groupid but that is not the biggest effort.
Think of JPA alone there are many XML files referring to Java or JCP.
Whether all get changed with Jakarta EE 9 or only the most commonly used remains to be seen.
