It has all the benefits previously mentioned in commit 2f547251, as well as mirroring the common programming convention of using a "_" prefix to identify private variables/functions Hides files beginning with _ from mod_autoindex listings As well as 404ing on files starting with "_", also 404 on files starting with ".", as these are also private. Except for /.well-known/, because that's... well known, and should be public.
Allows putting all the repeated stuff in one place (DRY!), so that if it needs changing it only needs to change once. Start the name of the included file with "@", and disallow the retrieval of files beginning with "@" (returning 404) so that it can't be downloaded, because it won't output anything meaningful. Why "@"? Because it's about the only ASCII punctuation character that doesn't mean anything special to most shells (bash), or programs, and is therefore easy to use as a filename on the command line. I almost went with "+", but it turns out that nvim treats arguments beginning with "+" as options. So "@" it is.
Rather than the generic "sans-serif"

<html> should have a 'lang=""' attribute, and </link> tags are not allowed by the spec.
