This would require a huge amount of retagging. (There are currently
over 1.5 millions uses of sidewalk=*.)

"yes" isn't the only value of sidewalk=*, there's also "right",
"left", "both", "no" (plus "none") and "separate". [1] This isn't
compatible with sidewalk=lane.

Why not inventing something different for a different feature? :)

[1]: As well as some less useful values like "this" (156 uses!?),
"bad", "both;right", "right;none", "10" or "forest". :D
