I look forward to seeing how the discussion progresses.

One way to improve surface=* tagging (and also lit=*) might be to
encourage people to install the Street Complete mobile app and try using
it when they go for a walk. It's very good at finding gaps even in
places mapped with a lot of detail.

On towpaths, they will often be tagged with highway=footway +
bicycle=permissive + towpath=yes. There are times when I would prefer to
use a route which avoided towpaths as much as possible, particularly the
Regent's Canal and places where boats are moored. Having them mapped is
one thing, but persuading any developers of routing software that there
might be enough demand to add it as a routing option is another.

Asking people to add data at street crossings (particularly crossings of
segregated cycle tracks) like dropped kerbs and tactile paving might be
helpful in this respect, even when it is not of direct use to cyclists.
It might not hurt LCC's case to be seen to be assisting VI pedestrians.
