Derriding "Just saving a bunch of stat calls" is a way to get lynched by new-httpd :)

Seriously index.html has 28 language/charset variants in apache-1.3, 35 in httpd-2.0.
Let's call it 40 by year-end.

There are 30 ways for a request to die with a 4xx/5xx response.

Let's say 1200 files :(

The most painful thing to mod_negotation (or mod_autoindex, for that matter) are directories
that are _too_large_.  The most painful thing to the stat call is, the same.

So instead of 1200 files, we have 30 files.  Each one serves a specific error, so that file
is accessed directly.  No multiviews, one file read, and the error is served _right_ _out_

_of_ _that_ _file_!

It's essentially manditory.  Anyone who has p/w protected (or removed) a huge chunk of content,
only to watch 50 spiders come in and fail on their refresh, would be very glad that these
not found/auth required requests didn't consume much cpu/memory.
