Fails with falcon on 3.13.

No rush. Let's wait for Falcon 4.0 to ship. A RC has been published two days ago.

Yeah, I'm cool with that. For the record, I have a pretty good guess about the build failure.

For some reason, setuptools is failing to pick up the falcon.__version__ attribute when building.
But also, I notice that their build uses Cython, so I bet it's a complex build process and not perfectly captured by the [build-system] table.

I'm betting that for all of the older Python versions, we've been getting wheels for falcon, but that there is no 3.13 wheel. That would mean this is the first time we've hit a requirement to build from sdist, and it doesn't work smoothly.

I was doing some personal cleanup and saw that this was still in my queue to handle. Falcon 4.0 is out, so I figured I should rerun CI and probably merge this.

Unfortunately, there's a new and different failure to handle, and we'll probably be best served waiting for this one as well.

3.13 removes cgi amongst the "Dead Batteries" declared in PEP 594. webob uses cgi, but it looks like they're not only working to handle it but also might "shim" it for a bugfix release.

I don't have a strong opinion about how webob "should" handle this, so I just look forward to picking up on their new version when it's ready. Our builds are grabbing webob==1.8.8, which is their latest, so I see no reason that we wouldn't be able to use the fix when it's available.

webob shipped new versions; I think we're good to go. Merging!
