Because there are walking paths with names, and that's not what you're
What you want is essentially a reference to another object, which is
why relations are useful- but they're complex to work with.
Additionally, using any name reference means that you now need to keep
the two objects in sync in non-obvious ways.
Let's take an example from NYC.
If I had a sidewalk for 6th Avenue, what would the associated street
tag name need to be?
Avenue of the Americas
These tricky edge cases aren't insurmountable, but they add a great
deal of complexity to software needing to parse the data in a
meaningful way, the end result of which is that more times than not,
if the data model is too complex, the programmer simply doesn't
That's why I advocate using tags like sidwalk=yes/no/left/right/both
