    root /path/to/server/root;

    location / {
        try_files $uri @fallback;
    }

    location @fallback {
        include /path/toparams_uwsgi;
        uwsgi_pass ...;
    }

Short answer: because "if" is ugly hack, see 
http://wiki.nginx.org/IfIsEvil.

Long answer: "include" isn't something special per config file 
syntax, and should be explicitly supported by every directive 
which takes block as argument.  In it's turn "if" takes block as 
argument and doesn't explicitly support "include".  And nobody is 
willing to dig into it due to already outlined reasons (see short 
answer).
