In contrast > highway <https://wiki.openstreetmap.org/wiki/Key:highway>> => path <https://wiki.openstreetmap.org/wiki/Tag:highway%3Dpath>>  + > foot <https://wiki.openstreetmap.org/wiki/Key:foot>> => yes <https://wiki.openstreetmap.org/wiki/Tag:foot%3Dyes>>  + > bicycle <https://wiki.openstreetmap.org/wiki/Key:bicycle>> => yes <https://wiki.openstreetmap.org/wiki/Tag:bicycle%3Dyes>>  is more clear what is its meaning."

If > highway <https://wiki.openstreetmap.org/wiki/Key:highway>> => path <https://wiki.openstreetmap.org/wiki/Tag:highway%3Dpath>>  has the default implied access values > foot <https://wiki.openstreetmap.org/wiki/Key:foot>> => yes <https://wiki.openstreetmap.org/wiki/Tag:foot%3Dyes>>  + > bicycle <https://wiki.openstreetmap.org/wiki/Key:bicycle>> => yes <https://wiki.openstreetmap.org/wiki/Tag:bicycle%3Dyes>>  (and horse=yes) then that means that an armchair mapper should add access=unknown to the tagging.

(1) access=unknown is very rarely used in way that you propose (and no editor is
 encouraging such use)

(2) it wpuld anyway not change that
"explicit tagging of access repeating what following tables imply may be still useful"
and that access tags should not be removed just because it matches what is currently
default according to this wiki page
