Thanks for refactoring!

Splitting stuff into more files can be good, but sometimes it creates unnecessary indirection that then leads to more context switching when trying to understand the flow. Same for splitting stuff into functions. Left some comments about that.

Also: I haven't checked the implementation details at all, since as I understand this is just a restructuring with no logic changes, but let me know if that's not the case.

[pabloDeputter]

Yes, the first 2 PRs are only refactoring. So no logic change.
