Any reason not to SSI include Registry scripts?

[Michael Todd Glazier]

As a way to speed up the CGIs but allow my designers easy access to 
the html file, I'm executing an Apache::Registry CGI script from 
within an .shtml document using #exec cgi . The Apache manual says to 
prefer use of #include virtual, but that doesn't pass the query 
string from the request. In a way this is a hacked template system. :)

Is there a reason, barring the known fact it would be faster as a 
full blown module :), not to use this set-up?

Thanks!
