I think that crowd does exist, but I've only ever seen them complain
about URLs and other wire protocols (where turnaround time can matter
a lot in terms of responsiveness of network applications for short
requests, and encode()/decode() cycles can really add up). Filesystem
access is dominated by I/O time, and there's often going to be some
encoding or decoding going anyway (since the app and the filesystem
have to get the data into a common format).

Cheers,
Nick.
