It's not clear yet how a change in the core module will impact other modules
that depend on it.  But, in principle, only if you remove a class from the
core module (or rename) will you need to rescan every other modules.
 Modifying a class' methods or functions inside a module will not have
impact on other modules[1].

I think not all the problems can be immediately foreseen.  We have to try,
and see how it works.

[1] there will likely be exceptions, like, adding a pure virtual methods
that makes a class abstract, where before it was not, has a big impact, even
on other modules.
