I cannot answer that, maybe someone who is knowledgeable about
uri-http.el chimes in.

RFC 7231 allows clients to attempt to DTRT with invalid Location URIs
in any way they deem appropriate; you could argue for a different
recovery heuristic. Me, I’d rather have things break loudly on each
violation, so that it does not go unnoticed for too long. Postel’s
Razor is how we got HTML in its current shape.
