Ahhh...I know that. It is not too difficult to determine some GEGL operation values and check them. Open up Filter -> Generic -> GEGL Graph and as an example this is the same as Colors -> Temperature 

   

You can even use that in a python plugin (or two) this is my test plugin and I can process three negatives in 20 seconds https://i.imgur.com/l1P5JQo.mp4 That can also be used in BIMP, that is what I use it for.

***but*** as Donald Rumsfeld said "there are know unknowns and unknown unknowns"

I know that Stephen Liu uses Ubuntu 20.04 and Gimp 2.10.18
I do not know if Stephen Liu has gimp-python working with this installation.

A python plugin might be useless. However in the spirit of things the plugin(s) attached.
