Actually: No. If interpreted straightforward, your example would end
with the line
abandoned = yes => I have an abandoned primary road with ref 58 that
was called Foo Street
The tag just adds another property. A client might chose 5px-width and
red color because it's a primary road. It might not interpret the name
- because for its application the name doesn't matter and the client
may decide whether to display it or not because it is abandoned. No
difference, just another choice.

Nevertheless I do understand the "*actually*"- and espacially the
"PITA"-part. So I am willing to accept the OSM-mission and join the No
History Club.
