I suspect the US holiday weekend means some folks are still catching up
on email. I have tried to write this down on the wiki:
https://cwiki.apache.org/confluence/display/TOMCAT/Jakarta+EE+Release+Numbering

I plan to allow a week or so for dev@ comments and refining of the plan
before starting a discussion on users@

I'll also seek feedback from the Spring folks as $work as that
represents a reasonable slice of our Tomcat's user base.
