I have to agree. Perhaps it's just my ignorance, but when is the
direction that the nose is pointing useful information?

In motorized IFR flights, ATC may ask for your heading and speed. Based
on that information and their radar plot, they can calculate the wind at
your altitude. This is useful information to them plus they then can
vector you by giving you headings.

Not much useful information in a glider, though, as long as your glide
computer works. If however you suffer a power failure in unknown country
with no distinct landmarks and/or poor visibility, I can tell you that
you will be glad to have that gadget. Dont' ask me why I know.
