Yes, although there is sometimes a gate in the back with no regular
key card access (it might even be padlocked) which is not for regular
use.  It would be a shame if both these and those normal "residents
only" gates were tagged with the same access tags.

Although, now that I think about it, the best solution for routers
might just be to group sets of gates together with a relation, and let
users manually select which sets of gates they have access keys for.

There's still the "one way" problem, though.  I think oneway=yes is
probably correct, but the semantics of which way is which is ambiguous
(even if you say it's based on the underlying way, is it oneway=yes in
the direction the gate is locked, or oneway=yes in the direction it is
unlocked?)  I guess one hint would be that the access=private way
would tend to be on the "inside" rather than the "outside".
