What does this PR intend to do, and why? The code changes make very little sense to me.

Sorry, I was updating the description. This basically adds support for path parameters in axum
Before this PR, paths weren't recognized

Before this patch:

Then it has nothing to do with the axum-matched-path feature though, which is purely about the MatchedPath extractor from axum (which is not required for using path parameters).

Also why did you make serde_qs a default feature?

Lol it was a fail, sorry I'm going to fix that

Oh ok, I'm going to change that, thanks!

@jplatte Don't hate me but can you review this? I know that you are not payed but just to know if I must to change something 😭

[jplatte]

Sorry, I have very little time for open source at the moment. I left a small comment, I think the overall approach works (it's a bit hacky, but I can't think of a better solution without bigger refactors).

Maybe @tamasfe or @Wicpar can properly review?

This doesn't appear to be used for anything. It's inserted in one place, removed in another (without its presence being used for any branching).
