I suspect the "tags" you're talking about in other projects don't have
quite the same significance as they do in OSM. Can you give us an
example of what you mean?
xybot for example.
I see bulk-changing one tag to another in this way as being equivalent
to changing a method name in an open source library without changing its
functionality, just to make the name nicer. Anyone using that method in
their code will get a compilation error all of a sudden, but nothing has
actually improved in the library. You break some people's use of the
data without having a net benefit.
Which data consumers actually used this tag, and did they use the
Wiki form, the last tagging list discussion, Editor Presets, or just
invent their own idea of how to consume it?
To put it another way, if the edits could be done using a simple
algorithm, they haven't added anything to the OSM data itself, since
that algorithm could be applied as post-processing. It's just
rearranging deck chairs.
This is an argument that tags should never be unified, but somehow a
colossal document that lists every possible alternate tag be created.
Data consumers would also need to implement such a document in code.
On the other hand, an established tag that is clearly widely used by
data consumers must not be changed without the agreement of data consumers.
