Packages will be removed from experimental if it contains a newer version in unstable (a so called "NVIU" removal).
Which is to say if someone uploads to experimental with a fix, and someone else uploads to unstable without that change but a huger version, the experimental package will be removed.
We should find a collaborative team wide way forward here. Playing NMU games is not the best way forward here, we're all maintainers together.
Y'all should take a break for a day and why don't we come back to this with constructive ways forward? (Both of you :) )
