This was introduced at the time when modules were made subclassable;
before then, it looked pretty much like what you propose.

Have you found any situation where this particular operation was
time-critical?

I believe (without thinking it through in detail) that the generic
getattr/setattr routines are required in order to support subclassing
of modules, which people use.

So I think your suggestion cannot work, and I also think it is
unnecessary, so I don't believe it is worth the bother.
