To me, this sounds like you should turn off ZIP to directory conversion, not 
blindly all stream_filter's.

If there is no other option, we can put a input item option to turn them off. 
I'd rather avoid it, as I'm sure it will have counter side effects in the long 
run.

No. That's never going to work with the decomp filter. In fact, back then, 
access_filter's were a usability nightmare precisely because they were all 
disabled by default.
