Yes, actually that's rather like what I had in mind: a walking map of 

It was me, you see; I'm the overmapper!

I don't think the extra detail is harmful, and if one were to produce a 
map in which the footways were big and obvious, and the roads little 
incidental grey lines, then this data would be better off as ways rather 
than extrapolated from roads' tags.

Of course, it's that slippery slope again: at what point will someone 
come along and want to map footpaths as areas?!  Actually, the GIS data 
that I'm most familiar with (not to imply that I'm familiar with it at 
all, really) is that of Western Power, where every footpath /is/ an 
area, as well as every grassy verge and driveway entrance!
