I think there are both valid use cases.
But it might be best to make usage easy for beginners.
If somebody can compile gdal themselves they are probably not having issues
building the Python bindings. But I'm happy to hear if this is used very
often.

Maybe having libgdal and gdal as separate wheels could make sense if no one
solution can be found?

I have no overview over the licenses of the dependencies.
Is there an overview available?
Would limiting ourselves to permissive FOSS licences remove any important
features?

I would have thought about integrating that into CI.

That would definitely be helpful.
