FastCGI is possible with mod_proxy_fcgid and mod_fcgid, but this has 
some side-effects:
- mod_fcgid can't connect to php-fpm
- mod_proxy_fcgid doesn't pass DOCUMENT_ROOT to php-fpm, so you would 
have to setup weird rules or multiple php-fpm pools for every vhost

Since mod_fastcgi still works with some patching there's not a big 
issue at this moment.

I don't see real need for mod_php either, when I initially tested 
Apache 2.4 it was giving weird issues. I replaced the mod_php setups 
with mod_fastcgi + php-fpm a while ago. Though fastcgi adds some extra 
overhead, the event MPM brings much more advantages that makes it worth 
switching.
IMHO mod_php with ZTS is not a good alternative, it adds additional 
overhead and you're still not sure that 3rd party libraries won't screw 
thread safety.
