Please read and engage with what what I said above about not disrupting
existing users by just randomly changing this, silently changing how the
parameter operates will break any users that rely on the functionality
which is not going to help anyone and to the extent there is an issue
here it is only those users who would be affected in the first place.

This is not a productive discussion, please stop unless you have
concrete proposals that are considerate of existing users.
