The wiki doesn't (and shouldn't) document "access:foot" etc. there, but 
the tags that are used of this form can be found at 

Lots in that list don't fit this form; of the ones that do (such as 
https://taginfo.openstreetmap.org/keys/access%3AN3#map ) many are 
presumably local solutions to local problems.

Data consumers can choose to consume "access:blah" if they want provided 
that "blah" is fairly obvious and it's listed in taginfo. This doesn't 
mean that "access:foot" is a "good tag" though.

The current "designated=" list is at 
https://taginfo.openstreetmap.org/keys/designated#values .  Most things 
there probably need retagging on a case-by-case basis; as an example I 
suspect that "designated=footway" on 
https://www.openstreetmap.org/way/227007990/history is an orphan from a 
previous use of "access=designated", which someone then "tidied", but 
didn't look at the data that they were changing.
