For that matter, there can be major regional variations within the same
country, not to mention variations for historical reasons within the same
city. In Nashville, Tennessee, USA, where I live, the majority of the city
was developed post-World-War-II, meaning that residential streets tend to
be built wide enough to allow parking on both sides, plus two lanes of
traffic. However, there are a few named streets in what had once been rural
hamlets, later swallowed up by urban expansion, that are only a single
lane, with no room for two vehicles to pass each other, let alone park.
Assuming that a given tag such as highway=residential or highway=path
implies certain physical characteristics is a risky proposition.

That is very true - which means that assumptions based on country need to
be made by the routers, and presets that change based on mapping location
need to be made. ("German Cycleway" and cycleway come up when searching for
cycleway presets when mapping in Germany).
Just as we have a variance as to what is a "primary road" in a third world
vs first world nation, we can still have a consistent regional meaning to
what is a "primary" road. The same could be said of cycleway or footway.
What i consider a residential road in Japan might be thought of as an Alley
in the US because of differences in expectations in how wide, easy to
navigate, turn radius, pole placement, barriers and hazards, etc there are
- beyond simple residential access.
but we don't just make everything highway=yes and define the differences
through subtags.
There are even more specialized tags in residential - a living street,
which is a regional tag. Why not have highway=cycle-ped_path (and a couple
others?) to fill in common situations? They could be rendered purple
(red+blue). A regional mapper could choose the best one for their area.
But i still feel that going by assumed purpose (a sidewalk is a footway, a
bike path along a river is a cycleway) regardless of what is
legal/permissive to use the way for (add foot=yes or whatever as necessary)
would better reflect the "duck" qualities of the way being tagged.
The easiest short term solution is to fill in some kind of "trail"
substitute for true "trails" that are maintained, like rural hiking courses
or narrow, rough paths through nature, which would take a lot of the "path
through the wilderness" burden off of =path, and set up for a change in
rendering/meaning for path in the future - if you don't need to tag =path
on anything, then eventually (a long time from now) it can be depreciated.
