So:
Mutton Lane, Market Alley/Avenue: I agree with you on these ones.

Rochford's Lane: I mostly agree with you here too. ViriatoLusitano mapped it in its current form, with an earlier version (also from V.) having been a footway, so clearly I'm not the only one who sees it as an edge case.

Market Lane: Actually started on OSM as a footway and was changed in 2020. Your change to that one still has effect. I'm 50/50 on this one, It's wide enough that I'd probably make it a pedestrian street but it's certainly on the cusp. I'd be curious what others think on this one.
