Map API question to help fix old addon

[Machinelf]

Trying to get an old addon (Equipped Forager) that worked only in Pandaria after the Map API changes in BFA. The offending line of code is

if GetCurrentMapContinent() == 6 then

"6" corresponded to Pandaria. AFAIK the new ID is "862," but GetCurrentMapContinent is no more.
The new APi seems to be still in development, and I could spend a few trying to plug things in and out, but /dumping all the new Gets returns nil in game so I am asking here first before i dive further in.
Does anyone have simple replacement for the line above? I have tried to look through other addons on Curse to see how others may have done this to no avail.
The addon works fine if I comment out the line above, and the "end." But it absolutely has to be manually disabled when not in Pandaria. Which is a PITA.

Edit: found it
local map = C_Map.GetMapInfo(C_Map.GetBestMapForUnit("player"))
local parent = C_Map.GetMapInfo(map.parentMapID)
if parent.name == "Pandaria" then
