sure, but actually avoids bothering with that setting in the first place for most
simple setups, so could be a net benefit.

hmm, yeah.. iff, it should probably happen in a separate get_protected_limit($scfg)
helper and we get the rpcenv singleton in other, rather deep, code paths too, so
not a big issue IMO, but not to hard feelings here.
