Do you have a rule of thumb on how likely a breakage is / what to look
for in NEWS?

If a package, rather than testing for features (what are the sort of
features one could test for in vala?), feeds e.g., vala>= 0.20 to
pkg_check_modules, then one has to keep a copy of vala-0.20 around,
and so on for all the various vala using packages?

Yet a single glib and a single copy of gcc will do for other packages?

I hope I am misunderstanding...
