You are using a fairly outdated version of AVRDUDE.

In recent versions (6.x), I don't see a problem with the way it is
now, i.e. using "lock" for the Xmega lock bits:

There are certain points in the code where m->desc is checked against
just "lock" so "lockbits" would fail to be recognized (i.e., just the
opposite from what this bug report is telling). In all situations
where this might be applicable, I changed the comparison to only check
for the first four characters being equal to "lock", so both, "lock"
and "lockbits" will do.

"lock" in the configuration file is not recognized by avrdude.
If it is renamed to "lockbits" in the configuration file, reading and writing of lock byte works.

Command parameter should remain the same though.
For example "-Ulock:w:0x00:m"

Well, we traditionally named the lock bits section "lock", not
only for Xmega devices but also for older AVRs.

What's your actual problem with that name?

avrdude.conf consists non-valid memory sections names for MCU's ATxmega family. Memory section name (in avrdude.conf) "lock" - is wrong, "lockbits" - that's right.
