They continue to work without any loss of functionality. (After the
follow-up patches to keep dynamic debugging and lock debugging
working.)

Now you can look for (O) after the module name in a BUG/Oops message
and you can tell whether the user really had the original or
compat-wireless version of the driver.
It is really up to each distributor or developer how they treat
bug reports with the O taint. When handling Debian bug reports I
won't automatically reject such a tainted kernel but I will look
carefully at the module list.
