This along with pydantic [0] means that 2/3 of my favorite python open source projects are now commercially backed. I wonder how long FastAPI will last?

As an aside, what is the issue with versioning these days? Ruff and FastAPI both have massive user bases and a reliable codebase, but haven't released v1.0.0! Ruff hasn't even got as far as v0.1.0.

You aren't the only one that has noticed:

More seriously though, for these projects, the first version is version zero. If they make no major backward incompatible changes, why would they ever release a version 1?

Because version 1 is the first version with any actual guarantees: https://semver.org/spec/v2.0.0.html#spec-item-4
