I agree with you completely.
I am running a wordpress(es) only as PHP application.

All wordpress static content like images, js/css files are served via CDN.
So as far as typical static content is concerned nginx have no considerable load to worry about.

Then another "static" content comes from output of PHP cached as static html files.
During my last test, after "caching" was done, I stopped fastcgi-php & mysql server and as expected request still served by server. Of course back-end was completely down in that case.

It is backend and some portion of front-end which amounts to PHP load.
And I am putting efforts to make backend faster compared to its current load time.
