(ie disable any redirections for `/foo/{.*}` but keep it for `/foo/{.*}/`. That would mean `/foo/bar` and `/foo/bar/` wouldn't trigger the redirection for route `/foo/{.*}`, breaking the "not-semantics" property of trailing slashes for catch-all routes. Which might be legit afterall.This PR implements this fine tuning, as that's the most BC behavior (and thus the correct one).See#30012 for `testGreedyTrailingRequirement` in action on 3.4 as a proof.Commits-------2bb8890 [Routing] dont redirect routes with greedy trailing vars with no explicit slash
