Sometimes tooling can generate unstable files, I recall there was time when Eclipse was notorious there, for example when saving XML files they liked to reorder all the attributes. But these are bugs that need to be fixed. Tooling should generate perfectly reproducible files.

Probably depends on the project as to whether this is feasible, but for us we intentionally want to generate everything we can in order to reduce systematic errors.

Mostly this helps with people simply forgetting to re-run the generator in their PR but it's a useful defence against people trying to smuggle things into the generated files, too!
It works on other systems because they emulate or virtualize enough of a Linux system to make it work. That's all fine, but comes with serious trade-offs in terms of performance, system integration, and things like that. A fair trade-off, but absolutely not host-platform independent.
