Good point! And as a matter of fact I got the same comment from Jon
Masamitsu when I first drafted the JEP. I promised Jon to change the
title of the JEP. Unfortunately I just changed the title of the wiki
page that contained the draft - not the field in the JEP template that
contains the title information.
I've changed the title of the JEP now. I'm not sure you think it is
better, but it is at least what I had promised Jon. The new title is:
"Remove GC Combinations that are not Used Enough to Warrant Future Support"

I thought "embedded" were building with a very limited set of GC support
and explicitly excluding all GCs except the serial collector.

Yes, and there is also the issue of being able to test and verify the
quality of the combinations. At the moment we have about 9 combinations
but we only have resources to continuously test 3-4 of them. I feel
very uncomfortable recommending customers to run untested GC
combinations in production.
Thanks for the feedback!
