I think having too much CGI on my server would kill it aswell, I'd say we should really think about PHP, as its really fast and also has the ability to do flat files as well as Databases.
In this case, i'd definately pick PHP as it will be perfect in the long run.
And you Could create .php pages from the Admin CP if you wish. Thats just up to the Coder(Developers) to add as a feature.
Just my $0.02
