Hi Rich!
To clarify, the current behaviour is documented.
It is also worth noting that passing an empty :only is the only mechanism
for you to fully unimport a module:
# It was imported it, but we don't want it
import SomeModule, only: []
Therefore if we change it to what you propose, the above no longer works.
There are also some advantages for not "merging" imports, as proposed, as
merging means one would need to look up at many difference places to find
what is actually imported.
In any case, regardless if you agree or disagree with the current rules,
changing its behaviour would be a strong backwards incompatible change.
