I discussed the name with Endre (@gamesh411) in person and our best idea is `inline-functions-with-ambiguous-loops` which would be the opposite of the currently implemented `legacy-inlining-prevention` (i.e. the default would be `inline-functions-with-ambiguous-loops=false` which is equivalent to `legacy-inlining-prevention=true`).

What do you think about this name? Would this be acceptable for you?
