I’m no Pythonista, but would it work to create “python-matplotlib-qt”,
which would contain nothing but the Qt rendering backend?
That way, assuming rendering backends are searched for at run time,
people could choose to install python-matplotlib-qt if they need this
backend. (Similar to what I did with ‘guile’ vs. ‘guile-readline’.)
HTH,
Ludo’.
