Why would you stop someone from working on SLAB if they want to?

Forcibly enforcing a freeze on something can make sense if you're
in charge of a team to conserve resources, but in Linux the situation is
very different.

Everyone works on what they (or their employer wants), not what
someone else wants. So if they want slab that is what they do.
