Hello Mark,

There are people on this list with more background knowledge in this 
area, but robots.txt was probably the earliest example of a fixed link. 
Then came favicon.ico. These are historic artefacts that are difficult 
to remove.

After favicon.ico, people in the IETF, the W3C, and elsewhere started to 
realize that this was a bad idea and created explanatory texts such as 
RFC 3205 (later updated to RFC 9205), and mechanisms such as .wellknown 
(RFC 5785, later updated to RFC 8615).

.wellkown essentially makes the mistake of defining a fixed link 
(prefix) for one last time, and then stuffs all future fixed links into 
the /.wellknown/ directory, governed by a registry at IANA to avoid 
collisions.

Regards,   Martin.

However, it contradicts something like section 2.3 of RFC 9309 (https://www.rfc-editor.org/rfc/rfc9309.html#name-access-method) where a fixed URL path is clearly being used for a "robots.txt" file. Please correct me if I'm misunderstanding, but why is having a fixed URL path for something like "robots.txt" acceptable for the IETF, but not for a fixed URL path for RSS feeds?
