All the 404 stuff should be intercepted but aren't.

URLs with two consecutive slashes in the path are usually garbage/broken. But I remember some issue with the dev server related to double slashes (pallets/werkzeug#822). Can you try if it also breaks when using a real WSGI container instead? gunicorn is probably the quickest way to test this.

Currently I only have gevent WSGI (where it happens as well).

The regex for PathConverter matches anything that doesn't start with a /, as absolute paths are typically a bad idea to let users enter. If you need your own converter that does something different, you can write and register one the same way the others are.
