We never followed such logic, AFAIR.  Quite the contrary: we tried to
delay loading as log as we could.  So maybe, for example, loading
diff-mode just because a VC backend loads is not TRT.

More generally, I'm afraid that not keeping this stuff in check will
be a slippery slope, which will quickly lead to a much fatter Emacs
process.
