Actually my problem is that SCRIPT_NAME is not defined in uwsgi_params.
SCRIPT_NAME is a mandatory environment variable as per HTTP/1.1 spec.

That's a major issue. A standard WSGI application should be able to use
a uWSGI upstream server within the "/" location block without the need
to define any "mountpoints".

Correct. Attempting to rewrite PATH_INFO as DOCUMENT_URI seems not a
reliable solution for my simple use-case.

A $uwsgi_script_name variable would be a worthy addition.

Note that I don't use fastcgi_split_path_info. The only modification I
did to fastcgi_params is:
fastcgi_param SCRIPT_NAME $fastcgi_script_name
fastcgi_param PATH_INFO $fastcgi_script_name
