I not sure I like this.

The URL dispatcher is a WSGI middleware, so it is ok for me to do this
in the url dispatcher.
I would like to keep the numbers of middleware to a minimun (function
calls in Python are not cheap).

Yes, that's an idea.
Note that this is a special case of an "URL normalizer" middleware.
A middleware can be used as a function decorator.
This is a point in favour to use a dedicated middleware for this.
