I thought we agreed that a spec's project page would list all compatible implementations? Not just the implementation that was used for the ratification ballot.
The process is that any implementation that has passed the TCK for an individual specification and is in compliance with the EF TCK license can do a certification request against the spec project. The project reviews the request and if acceptable adds the implementation to the spec project page's Compatible Implementations list.
For example, if Jetty met the requirements for
Jakarta Servlet they could do the certification request and be added to the list of Compatible Implementations
We loosely describe this process in the
Jakarta EE TCK Process, see Certification of Compatibility. The language in that section needs to be tightened up in my opinion since it mixes considerations for getting listed on the
Compatible Products page for compatible implementations of the Platform and Web Profile with what I described above.
