Sadly, all proposal without a change within some time period where set
to abandoned some time ago. Please feel free to take over and reactivate it.

Actually, I am in favour of creating more keys in stead of too much
grouping. We already get conflicts with highway=traffic_lights vs.
highway=crossing and imagine traffic_calming=* to be under
highway=traffic_calming.

I would propose to use man_made=quay analog to pier and guess that there
are not many natural quays.
Still waterway=quay is used a little more often [1], so documentation
and some con-sense is needed.

waterways are all linear objects and it contradicts to your
waterway=quay/wharf

I would not take all keys literally and we will always have a discussion
about natural=* I guess.
