We don't have such usage yet.  rdmacg would be the first one doing
something like this.

That doesn't sound like a good idea.  What happens when the amount of
available resources changes either through underlying resource changes
or config changes in one of the ancestors?  What "max" means is "no
limit is imposed" which is different from "limit it to 100% of what's
currently available".

Thanks.
