I wonder ...

Given that we don't want to have full GDB tests which check that STL pretty
printers work (for fear of libstdc++ implementation changing underneath us),
and libstdc++ can't test these printers at all (they'd need a capable GDB
to do so, which isn't going to be generally available for a while), who
is going to maintain these printers at all?

Since the printers are versioned, and (AFAIU) libstdc++ implementation
can not change in v6 (that would break binary compatibility), would it not be
better for us to maintain libstdcxx/v6/ (especially given that
any required maintenance would likely be due to GDB/Python internals changes,
not changes).
