[Gimp-user] c2g in Gimp 2.10.12 not performing as in 2.8

[pistikem <forums gimpusers com>]

you are absolutely right, rich404, i observed the same changes in c2g's
rendering pattern with the version changes in GEGL and GIMP, via GUI or CLI.
now, this is very unfortunate. the c2g algorithm is to my understanding truly
unique and very unusual and special, as it adjust pixel contrasts in an 'organic
or neurological or physiological' way, like the original author stated that he
was influenced by neuro-physiological evidence.
i feel this precious piece of code would deserve to be properly maintained
within GIMP and GEGL, or be made publicly available, perhaps ported to Python3. 
i am not aware of any other (photo) image processing algorithm that
'intelligent' to combine data-driven(!) contrast and color information from a
pixel neighbourhood across three channels for the purpose of reducing RGB to one
layer.  i am truly desperate for getting a new c2g version to work with the
appropriate set of adjustable run parameters.  what about a python3 port ?
i still have a few linux boxes with gimp 2.8 running but i don't see that as a
good way out of this problem, perhaps as a temporary solution only...
