Apache2 SAPI

I've been using the apache2handler on two low/medium-traffic sites for a 
while and it appears ok to me.

now.. I'm new to this list, and really don't know how it works, so 
excuse me if this is a FAQ or something.

I'd like to see this code in 4.3.2/4.3.3?, and if it doesn't blow up,
replace the 'apache2filter' as the default apache2 SAPI in a month or two.

so..
Can I check this into PHP_4 & PHP_4_3 ?

Thanks
Ian.
