Motivation
The current
route_layerdocumentation incorrectly implies that middleware applied viaroute_layerwill also run on the fallback route. This is not the case, and this PR clarifies the intent.Issue #3421 was created, with a PR to correct the bug in the documentation. However, that PR has been stale for multiple weeks.
Solution
