[pytest-dev] sorting out broken config initialization - by doing major releases with api breakages

[RonnyPfannschmidt]

Hi everyone,

currently pytest configguration initialization is pretty much broken in
many details,
and as far as i can tell its going to be even more tricky to try and fix
than marks,

i will not again go trough the pain that i had with marks and want to
sort out a gate
to lift and change detail apis that will be broken.
