My preference is to go with what we've been doing more recently (do _OPTIONAL) so that
consumers handle things properly and we don't have to try account for various cases
(this was the problem with eclass variables which add a USE flag or depend only
if a USE flag is set).

But that said, I can't immediately think of any such annoying edge
cases with this idea. It'd be additional to GO_OPTIONAL and it'd
ensure a sane baseline Go version is chosen. So, why not?
