I'm not sure to understand this, I should probably see the code.

But all that I'm saying is that gi.repository imports are supposed to have
virtually no performance impact, as we have also verified stracing. Big or
small library doesn't matter.

If they do have a performance impact we need to understand why, before
trying to work around the problem by moving imports around.
