I could understand if it was doing this within pdb2gmx or something
that was constructing a topology file. I'm observing this behavior
when using editconf to simply convert files to another format or apply
box dimensions etc. Anyway, I submitted a bugzilla about it. This
isn't such a big problem - make of it what you will. ;-)

Don't bother for now :-)
This is because of a few old brain-dead choices in pdb2gmx, but we're
working on replacing that completely, and then we'll be name-agnostic.
The only thing I can say in our defense is that most other programs
also push their own naming convention when generation hydrogens, etc.
For instance, charmm will rename the resname of the first/last few
atoms in each chain to NTER/CTER.
Cheers,
Erik
