because when it was first put in someone wanted a switch to
be able to disable it and therefore it's a new CLI addition
and it was put in originally as off by default.

Once that path is started it's almost impossible to reverse
without someone complaining.

IMO it should have been an internal change without a CLI
to toggle and it been done everywhere.

If I can find the time I'll check and see if it is on
by default anywhere and maybe start the process to do it.
