Yes, this should have been detected.

I am not sure I understand: it is expected that building software A
against B >= 1.3 cannot run with B < 1.3 (forward compatibility). It
is the same as a runtime error when running something with libfoo 1.2
but linked against 1.3, using a function 1.3 specific.

We should fix the undetected incompatibility, but I don't think we
should care about the incompatibility itself.
