Description

Some applications are written against std but don't require too many features. The most popular ones are IO-related, thread-locals should be also trivial (and useful), anything doing synchronization (there are no threads; attempts to create threads should not compile).

Potentially also allow virtual filesystem. TCP would be nice but likely controversial.

Unfortunately, I think this requires either pinning the compiler version or provide std for every supported version.

Research direction

No files, tests, or entry points are named. Start by reviewing the project's supported compiler versions and how applications currently access std. Define the supported IO and thread-local surface, ensure thread creation does not compile, and resolve whether virtual filesystems or TCP are in scope before implementation.
