I wouldn't say it disables read watchpoints, since the functionality GDB
provides is exactly that; read watchpoints.  The difference is that it
uses access watchpoints to accomplish this, because a large set of targets
does not support true read watchpoints.

Which is more important; providing the functionality, or providing some
functionality for some targets, but using hardware read watchpoints instead
of hardware access watchpoints?
