Wait, if we are arbitrarily putting words in people's mouths this might as well have been how it went:
Me a random dev: Hey I really like your mod when I tried it, but I am more used to many of the similar mechanics from other mods; your rednet cabling really exceeds anything else and I enjoy using it a lot. I noticed that you have options to have themed alternative recipes for many of the blocks, thanks for this, it has helped me balance my game a lot. The one thing that sticks out to be is the price of the rednet cables, plastic ends up being really cheap with a smelting system and a rubber farm setup, cheap enough to not amount to almost anything with my infrastructure. It ends up seeming like a trade of three redstone dust (three blocks worth of travel) into 8 pipes (8 blocks of travel, including perfectly vertical). I think it would be a genuine help to player's balance if you were to allow the output to be configurable. Thanks
Modpack makers: You need to give us thermal expansion recipe options or it doesn't make a single ftb pack, there are other mods we can use.
The config option is literally the easiest config option I can think of to implement; it is just a integer variable (by definition "less complex" than strings, floats and doubles), and this gets placed directly into the recipe registry instead of the hardcoded 8 which it is now. The default would still be able to be 8. If another dev could come and tell me that it is not as easy as I am making it out to be, I would be impressed.
