A couple of things on the asp/cold fusion/whatever serving up dynamic CSS

The important thing here is the security of the DLL itself. Adding file 
extensions to the one mapping you ARE allowed to use (asp.dll should be
the only one in use, the others that come installed by default basically
turn your new webserver into a $15,000 sieve) is absolutely fine [1].
It's important to reduce the non-essential DLLs used in mappings, not
the mappings themselves.

(don't worry, I'm used to it, believe me!)

    any security holesd cause by some previously unknown IIS security
    bug due to file EXTENSIONS, not mappings, like filename extensions
    with non-7-bit-ascii characters in them, dashes, underscores,
    periods, or, knowing microsoft, the letter 'e'.
