The draft was initially proposed as informational but with the support of the 
area director, the last call was made to promote it to a proposed standard. 
Assuming there is no objection, we would like it changed to standards track.

The problem is that the registry is only for well-known location documents 
located within the /.well-known/ prefix. Since robots.txt and other such 
document (p3 and cross domain for example) are located in the root, adding them 
to the registry will cause confusion since it will change their expected 
location:

http://example.com/.well-known/robots.txt

Proposing such a migration is not likely to make any actual deployment 
difference (the millions of sites using it already are not likely to move it or 
copy it), but is likely to confuse new developers.

I think what is more likely is for future versions of these files and new files 
to use the registry and avoid collision.

What we can do is include an appendix with the list of all known well-known 
locations outside the new prefix to help in documenting existing practices. 
However, that is not likely to be complete and might cause a long delay in 
publication.
