Describe your use case and the problem you are facing

wp server does not handle wp-login.php and, more generally, any WP entry-point other than index.php

Describe the solution you'd like

Hardwiring entrypoints logic (or even parse the htaccess using PHP) in order to support them would make it.

A fully browsable WordPress instance off Apache/nginx/php-fpm would be handy in Q&A situations/simulations. The (probably < 100) lines needed may be worth it.

If login.php is requested by the client, that file would be require'd dynamically.
Some tweaks to $_SERVER may be needed though in order to mimic mod_rewrite behavior.
