I think you mean "indirect" deps (level 2)? To me, "direct" deps and
"level 1" deps are the same thing?
But what about updates. If a new version of 3 builds with a different
soname, both 1 and 2 need to be rebuilt. If 3 is not listed in 1's
REQUIRES=, how will we know that 1 needs to be rebuilt? This is not a
theoretical question -- slackrepo already this kind of upgrade
automatically. (And it uses dep trees, not queues, so it doesn't
Of course if 1 has no code that uses 3, then of course 3 should not be
in 1's REQUIRES, but I don't think anything breaks if it is in
REQUIRES= ... just some unneccessary rebuilds when 3 is upgraded.
