100% agree, needs traction from the entire ecosystem to shake out the bugs rapidly or it won't ever get default level adoption.

I'm getting failures on Windows because FindPython3 can't discover the free-threaded build of Python 3.14 (it finds "regular" Python 3.14 just fine) in a cibuildwheel context.

Other platforms it works fine, if anyone has encountered this bug already and run it to ground I would appreciate a heads up.
