This does not solve the problem at all, as the network of streets and
side-streets sharing the same name can be arbitrarily complex.

What's needed is a direct relationship between one road segment and the
one or two sidewalk segments that belong to it. Grouping a large number
of segments that happen to share the same name does not help, no matter
whether it's done via name tag or street relation.

Therefore, copying the name to the sidewalk ways is simply a workaround
to aid one specific use case: route descriptions in pedestrian routing.
It does not fix the issue for the other affected use cases.
