Hi,

This name is not signed anywhere along the road. Supposedly, it was once the commonly used name, but as a local I only ever hear it referred to as "route 17". As such, I believe that noname=yes with ref="NY 17" is the appropriate tagging for the road.

Note that this does not apply to NY-17 west of Binghamton, which is a separately constructed road that does have a signed name.
