WGT/WGST seems to be a widely accepted abbreviation for the West Greenland Time zone.
As far as I can see, it's an invented abbreviation propagated from tzdata, and there isn't much independent support for it. I've been trying to omit these inventions, as tzdata should record timekeeping not invent it.
the removal causes certain things to go belly up
Which things went belly up? Details might be helpful. Tim mentioned that we've been trying to omit invented abbreviations. In response to your email I reviewed them, and see one that should change (namely, "BOST" for Bolivia Summer Time 1931-2, should be "BST" to be consistent with abbreviations used elsewhere; we can't change it to numeric due to POSIX limits). There is at least one other abbreviation ("SET" for Swedish Time 1879-99) that I'm suspicious of, but not enough to try to change it now. At any rate, now that I've pretty much finished the job we should document the alphabetic abbreviations used. To give that a go I installed the attached patch into the development version on GitHub.
