Since I installed a Gimp 2.6, I made a 2.6 xcf file to play with (attached for info)
Open in Gimp 2.10 and it is in legacy mode.
Leave it in legacy mode and color-to-alpha (c2a) which is now a GEGL procedure works as in Gimp 2.6 https://i.imgur.com/cQYOBxx.jpg
Change the mode to default, there are good reasons for the enhanced Gimp 2.10 color options, apply c2a and get that faded effect. https://i.imgur.com/BIpYGR9.jpg
It is possible to get close to the legacy version by reducing the opacity threshold, say 0.5, not quite an exact match, needs a little more transparency. https://i.imgur.com/Ldln5jA.jpg
