Yes, pretty much. What primarily bothered me was the soft/hard
guarantees being chosen by a toggle switch while the soft/hard limits
can be configured separately and combined.

I was wondering about the usefulness of "low" itself in isolation and
I still think it'd be less useful than "high", but as there seem to be
use cases which can be served with that and especially as a part of a
consistent control scheme, I have no objection.

"low" definitely requires a notification mechanism tho.

Thanks.
