It would be nice to be able to set and/or influence the heat and humidity of a node before biomes are chosen. I know mapgen_rivers has altitude cooling, altitude cooling could be implemented as such a function. For example, you could register a heat and humidity function:

biomegen.register_heat_humid_modifier(function(pos,old_heat,old_humid)
  return (oldheat - .025*pos.y) , (old_humid)
end)

so the function gives you the old heat and humidity (or if not defined by the mapgen?, assumes default values?) and then lets you return the modified heat and humidity. You could also have a variant that lets you set the humidity by mapchunk for noise-based modifiers.

My usecase is that I have a custom mapgen where I would like to have biomes strongly influenced by which quadrant of the coordinate system they are in. I would have liked to be able to make one quadrant drier and hot, another wet and cool, another temperate, etc (of course, eased as gaussian bumps)

I ended up not using biomegen:
