Or perhaps just simply "Retire some GC combinations", and say what you are
saying above but not in the title.

That's true of the "embedded" offering (thanks for the reminder). I was
thinking more generically of the Jav SE offering being
used in what might be considered "embedded" settings (such as routers,
network devices, switches, printers and so forth).
Not sure if there is such a market, or I am thinking of a phantom (insert
appropriate Shakespeare quote here).

I agree though that from the standpoint of server environments, less is
probably better, given the complexity of maintaining
the various combinations.

Yes, and there is also the issue of being able to test and verify the

Completely agree! I think this is a welcome step to keep the platform
evolving with the times and shedding vestigial organs, as it were.
