Research direction

Start by reading the py_compile and compileall entry points to trace how unwritable .pyc files are currently skipped. Define how an opt-in failure should surface, then verify that the option reports the write failure instead of silently continuing.

Written by the indexing model from the issue text.

Description

During testing upstream, it was found that py_compile, and thus compileall, silently skips writing .pyc files it can't write (because of path size limits; probably also because of permissions etc.).

For Fedora, it would make sense to fail with an exception (or error exit code). It should probably be an option – not everyone will want it.
