Not really. 
On windows they must be service programs, which are an absolute horror to debug.

Well, I switched from proxy fcgi to normal fastcgi for performance reasons.
It simply scales better.

With all the virtualization happening these days, introducing state on the 
server is a very bad idea anyway, so I would not recommend this approach.

As for debugging: 
it rarely happens that I must debug an actual running fastcgi program.
All code is unit tested, and the unit tests run in a CLI program.

The nice thing of web is that it is simply "text in, text out". 
Can perfectly be simulated on the command-line.
