This is exactly right, unrelated binaries can coexist, or different versions of the same binary, etc.

This is also right! I started building an application framework that could leverage this and provide some protections on memory use: https://github.com/jer-irl/tproc-actors , but the model is inherently tricky, especially with elaborate data structures where ABI compatibility can be so brittle
