What would you like to be added:
We know that node affinity/anti-affinity currently supports In, NotIn, Exists, DoesNotExist, Gt, Lt. But pod affinity/anti-affinity only works with regular label selectors: In, NotIn, Exists, DoesNotExist

FYI:
https://bugzilla.redhat.com/show_bug.cgi?id=1462543;
kubernetes/website#4137

Why is this needed:

I don't know why Pod affinity/anti-affinity not support Gt and Lt operators. If anyone knows please tell me.

My initial requirement was to compare two labels (such as "20" and "30"). I am considering whether pod affinity/anti-affinity should support Gt and Lt operators?

Just like @liggitt said #72556 (comment). Once #72479 has a conclusion, we are going to make this work part of KEP proposal MaxPodsPerTopology Feature Brainstorm.
