For bug fixes and security fixes, there is already something like
RECOMMENDED in pkgsrc, no?

OK. But, can there be any cases when it doesn't work AND it is not a bug
in the upstream software? Not increasing major number when ABI change or
minor number when a function is added count as a bug, IMHO. There is not
much that pkgsrc can do about upstream bugs. (Always recompiling
everything (make update) doesn't count, because you should always have the
option to recompile everything if such (hopefully infrequent) bugs in
upstream packages are encountered.)

HAHA :-)
