Phil, you need to read more carefully what's this about, because it's
way more complex than that.

This is an open issue for several years, without a seamless solution,
but I see this popping up many times when mapping.
I'm not very knowledgable about relations, and I'm sorry if I'm a bit
confused here, but doesn't a restriction relation means the exact
opposite of what's intended here?
I mean, I want to apply a STOP sign to a given lane (in a way with two
lanes, for example) and force its action to a given direction on the new
road ahead.
The wiki page for this type of relation doesn't mention STOP nor GIVEWAY
signs, but in the discussion page there this:
https://wiki.openstreetmap.org/wiki/Talk:Relation:restriction#Incorporate_.27give_way.2Fyield.27_and_.27stop.27_as_possible_restrictions

If neither relation scheme (enforcement or restriction) can be applied
here (for complexity or incompatibility reasons), why not use the
existing lanes scheme?
Like this:

|highway=stop stop:lanes=yes|no stop:turn:lanes=left |
