Why do you need to have multiple git repos contribute to a single module
instead of having each repo produce its own module? I don’t understand why you
would do that.
To me “module” implies “a cohesive set of code maintained by a single team”. I
trust people on my team, and I can also see every change that goes into the
projects I work on.
Again, if you don’t trust developers that are contributing code to your module
then you have bigger problems than this. Proper module boundaries would help to
address those problems.

This is contradicted by the experience of a large community of C# developers
who have been using partial classes for years without running into your
hypothetical problems.
A search on GitHub shows over 5 million hits for “partial class” in C# code:
https://github.com/search?l=C%23&o=desc&q=%22partial+class%22&s=indexed&type=Code
<https://github.com/search?l=C#&q="partial+class"&type=Code>
There are over 2000 hits in the Rosyln codebase alone (Microsoft’s C# compiler):
https://github.com/dotnet/roslyn/search?q=%22partial+class%22&type=
<https://github.com/dotnet/roslyn/search?q=%22partial+class%22&type=>
This is heavily used in the real world by professionals working on projects of
all sizes.
I think we have to weigh the FUD against what we can observe actually happening
in the wild when developers use a feature like this. The reality is that the
things you’re concerned about are not actually problems in practice. They’re
contrived hypotheticals.
