As posted on the Curseforge page, putting here (in slightly more detail) because I'm not sure which gets checked.

Would it be possible to add a server command that parses the entire world (all region files) for specific biomes?

Not sure if this is possible, but I'm looking for a way to ensure a BoP world has enough tropical regions to make it worth playing in that seed. That basically means finding at least 1 Jungle or Bayou or any of their tropical-climate biomes, in the entire world. (BoP devs have indicated they can't or won't fix how worlds sometimes don't generate any tropical bands at all, so the fallback is to generate many worlds until one of them fits the bill.)

This mod seems like the best bet for that:

• Amidst isn't compatible with my setup (cannot handle BoP, no word on whether or not it supports smaller mod biomes like Thaumcraft's, and devs seem to be saying no one's interested in adding the compatibility layer).

• There's no word on whether or not Geographicraft truly takes smaller modded biomes (like TC) into account, and it doesn't seem to support BoP's most recent updated biomes, so I can't really ensure specific biomes are in the world with that.

• All mappers I've come across for 1.12.2 require you to explore the world before they'll show biomes (Voxelmap, Journeymap...) or don't support biomes at all (unmined).
