I had an idea for how Terrestria could interact with Tech Reborn, more specifically with regards to how both mods add rubber trees of different types. I think it would be neat if Terrestria could detect if Tech Reborn is installed, and, if it is, do one of the following:

• Use an alternative name for the rubber trees denoting a variant, such as swamp rubber, and let Terrestria's rubber trees inherit Tech Reborn's rubber trees' property of occasionally generating sap that the player can harvest with the treetap/electric treetap/resin basin. This could potentially even include a variant of the resin basin with Terrestria's rubber planks colours.
• Or, perhaps more invasively, have Terrestria's rubber trees inherit the sap producing property, and then stop Tech Reborn's rubber trees from generating at all. This would make players search for a Cypress Swamp to unlock rubber production, making them explore more of their world, but would lock out a unique wood type.
  I think this could be neat, but, of course, it's all up to you.~

While I think that it would be good to have some level of integration with Tech Reborn, such as letting you get rubber from Terrestria rubber logs at least, I don't want to gate the entirety of TR progression behind being lucky enough to find a cypress swamp - that seems more like something for a modpack to do, if it's something that should be done at all.

I was thinking that that idea was a bit harsh as well. So my first idea still stands.~
