Try and convince a user of that :-)  This is, right or wrong, a 
situtation where we're the ones that get to push for a solution.

To that end, two ideas:

- add a GNU extension to dwarf2 that identifies the frame as outer-most

- have the CFI unwinds back to the exact same identical frame (causing 
GDB to throw up its hands)
