Hi Dom,
This is a bit unfortunate, but I think it is not a show stopper.
My thoughts are that:
* Python dependencies regularly misbehave, and while we try to keep
dependencies to a minimum, it is difficult to find a vector of
compatible versions which work together on all supported python
versions (currently 3.9 to 3.13).
* I don't think we can reasonably make a guarantee that BuildStream
can be installed into a host python environment on any/every fairly
recent distribution version, although it is often the case that it
does and we do try.
* This issue can be fixed in a follow up 2.5.x release, without
affecting BuildStream's API stability guarantees.
Cheers,
-Tristan
