Basically I want to pilot a few possible optimizations outside of the
SubstrateVM tree, some of which might be very specific to a particular
library.  Some of these might end up as upstream feature requests or
PRs to SubstrateVM, and some might just end up getting discarded.  But
regardless, any manipulation of the compile tree is not possible
without the more specific `GraalFeature` API AFAICT.

I'm not too worried about breaking changes because we're presently
mandating specific SubstrateVM version(s) to be used with the Quarkus
project.  But, I don't really want to force people to use GraalVM or
the Labs SDK to *build* Quarkus as it might really discourage outside
