How to make choices when nobody knows the characteristics
of the 8076 values ?
How to choose according to one's own criteria without a list
of criteria and the response to these criteria for each value ?
At the moment everyone is guessing: surface=ground -> not for bikes,
surface=concrete -> good for bikes. and no luck when it's not so

We're in an absurd situation where the more precise a data is,
the more unused it is because it would imply that everyone
1) detect the appearance of a new value in the list
2) understand the commonalities and differences with the other values
3) write code to implement the new value and its characteristics.
and this obviously takes place long after the database/wiki is updated.
Untill that, it pushes people to invent false information to force
the desired use. the surface is not suitable for bicycles?
some  add bicycle=discouraged or bicycle=no even without any sign.

To avoid this, it would be useful to have a list of surface
characteristics allowing you to treat them according to the criteria
of your choice (adapted to the vehicle, to the bicycle, in rainy
weather, ...).
In an ideal world, the contributor who invents a new value should
be offered to easily document these characteristics.
This would allow to have "any tag you want" *and* usable
