[Tagging] Meaning of access=yes on highway=footway?

And it gets even more complication with conditional.


E.g., there are tennis courts on asphalt that can be used for parking and driving at 
certain events a few times a year.


This path in the park near me
https://www.openstreetmap.org/way/4204572

will in about a month be used by huge trucks setting up stages, rides etc for May 1. 
celebrations.

We do tag foldable bollards which are often used to let e.g. moving vans and 
constructors into paved footways leading to residential building.

I have never seen access=yes that made sense to me on a footway or path.
but motor_vehicle=emergency and motor_vehicle=private does make sense.

There are paths and footways at churches and cemeteries that are routinely used by
hearses, busses for handicapped, etc. Some of them can be tagged as highway=service, 
but I do not think that path is wrong.

So it is complicated. An it would be unfortunate is wrong tagging with access=yes 
would result in routers ignoring efforts at tagging detailed access to paths.

and access=yes on highways are almost always also wrong (e.g., it is probably not for 
smowmobiles). So why not just fix wrong tagging in the database? And tools and 
editors should warn about using access=yes (maybe they do, I have not tried to tag 
anything with access=yes so I do not know)
