There’s also API Sets: where DLLs like api-win-blah-1.dll acts as a proxy for another DLL both literally, with forwarder exports, and figuratively, with a system-wide in-memory hashmap between api set and actual DLL.

Iirc this is both for versioning, but also so some software can target windows and Xbox OS’s whilst “importing” the same api-set DLL? Caused me a lot of grief writing a PE dynamic linker once.
