it doesn't actually create a more explicit relation than does
footway=sidewalk name=foo
both ways of modeling it depend on comparison of the street name.
Both might fail when there are several streets with the same name, or when
there is a typo or other variation in one of the name (or sidepath:of:name)

we have already discussed this, see your initial sentence. I believe that
renderers would adopt quickly if it became more widespread practice to add
names to sidewalks. There may be some issues during the transition time.
There are also significant issues from omitting the name (routing
instructions are typically not telling you the name of the roads on which
you are and which you have to follow, when you're on sidewalks or cycleways
along roads).
