Yes, I think where there are issues for pedestrian routing, that's a good
reason to separate out the pavements, though would sidewalk=both with
highway=crossing address that too? I've found that OSMAnd makes some bad
cycling and walking routing recommendations because it is unaware how much
traffic some of the roads carry, in which case it would be nice for a
router to have cues about the viability of crossing roads other than at
signalised crossings.

Out of curiosity, one of the issues a sight-impaired neighbour has raised
is that the use of tactile paving at street corner drop-kerbs is quite
inconsistent round here. I was wondering whether recording this somehow
would help identify where the problems are and also help with routers. Are
such areas considered crossings, though?

I just also feel that mapping sidewalks where there are no such clearly
designated crossings and preferred routing doesn't add any more than
sidewalk=left/right/both. Maybe it's a preference thing. It feels like a
potential source of really inconsistent mapping unless you plan to do it
for the whole neighbourhood?

There was a State Of the Map talk on "OpenStreetMap and the neglected
pedestrian" that I'm desperate to see, but hasn't been added to their feed
yet!
