Please add the option to disable caves in tectonic.json. I am making a server to play Reign of Nether RTS. And tectonic is very good at picking up mountains and making smooth geometry of the territory. But there are a lot of caves and I tested that the server works worse when there are tunnels.
and did tests

1. with tectonic
2. with tectonic + filled all the tunnels with blocks within a radius of 2000x2000 (worldedit mod)
3. without tectonic, vanilla generation, with caves turned off.
   Both the 2nd and 3rd variants produced more stable TPS and Tick ms in the stress test than the 1st variant.

Reign of Nether RTS is running on 1.19.2 Forge and may be updated to 1.20.1 soon (there is a beta file)
