Drop the now-vestigial expansion plumbing.
- Delete modules/thirdparty-tbc.lua + its xml Include
- Strip 10 tbc-tagged CreateConfig calls in modules/gui.lua
- Drop the expansion arg from CreateConfig() signature + the disabled-
entry rendering path that depended on it
- Drop the showdisabled GUI toggle + its default
- Simplify pfUI:RegisterModule / pfUI:RegisterSkin to (name, func) only
- Strip the leading version arg ("vanilla:tbc", etc.) from all 114
Register call sites
- Delete the pfUI.expansion variable
The byte-2-of-UNIT_BYTES_1 extraction this function did manually
(math.floor(b/65536) - math.floor(b/16777216)*256 on the GetUnitField
return) is precisely what GetShapeshiftFormID reads under the hood —
descriptor +0x212. Collapses to a one-liner that doesn't need to
mirror the engine's byte layout in Lua.
