True, but the changing a LGPLed licence to GPL on a new version
doesn't change the licence on an already released version.  The "old"
version would still be LGPLed.

If a LGPLed version was put out there, and then later there was a
switch back to the GPL for new versions of GPGME, then all of the
updates and new features/fixes would probably be provided on the new
re-GPLed version.

Users of the LGPLed version could either stay with the frozen LGPLed
version, switch to the GPLed version, or implement the features and
fixes they need (and then make them available under the LGPL).  Sort
of like a licence-mandated code fork.
