Jonah, do you have interest in keeping cvs support around or are you
just asking to check for options?
I have no personal interest in CVS - however I have one client who still uses CVS. I have asked them about CVS support in Eclipse going forward and I am waiting for their response. The answers to my questions were sufficient to put a proposal together for them.
However, this may simply be the kick they need to move their legacy stuff off CVS and onto git.
