uv lock and platform-specific resolution

[SamyAB]

The documentation says:

By default, uv's pip interface, i.e., uv pip compile, produces a resolution that is platform-specific, like pip-tools. There is no way to use platform-specific resolution in the uv's project interface.

Does the last sentence mean that there is currently no way to create a platform-specific lockfile with uv lock, or there will never be one?

If it's the latter, I am curious to know why.

The reason I am asking this is because it happens quite often that I work on both x86 and armv7l architectures, and having a lockfile for x86 that points to pypi-like registry and a lockfile for armv7l that points to a piwheels-like registry is very useful.

Thank you for the awesome work!

There actually is since #6210 — we need to update the documentation to clarify this.

That gets me 95% of the way there, thanks!
