Irish, I don't know that many, or indeed any, of the biome restrictions are working, actually. Or the profession restrictions for that matter.
Most quarries, factories etc can be built in any biome. My town has an oakfarm in a plains biome and that's not listed as a required one.
Also the soul shard regions aren't being restricted to their professions (although I would like to see that changed, lol). It seems non-Miners can build gold mines and thus I'm guessing redstone mines too.
The only mention I've seen so far of biome restriction was not being able to build a cabal because it was looking for mushroom_island biome instead of mushroomisland biome. (This has been fixed in the configs, but I have no idea what people are finding ingame).
I'm finding it a little frustrating because I really need to know what players are experiencing ingame. The wiki reflects what I see in the configs, but as with all coding, no one knows what does and doesn't work until it's tested ingame.
I would dearly appreciate players reporting to me whether they've found that ANY profession or biome restrictions are actually working.
