implementing communication with the wayland color management protocol

Does anybody here already work on implementing the communication with the wayland color management? So darktable can show colors outside of srgb without switching off system-wide wayland color management?

From my point of view, there will be no way around this. Chrome is the first program that can definitely do this. Krita and Digikam are working on it.
Of course, in darktable's case, there are at least two challenges: darktable uses gtk3 and porting to gtk4 seems difficult, plus darktable uses xwayland.

I did some research and it seems that there might be some "workarounds", e.g. chatgpt suggested to create a proxy that does the communication between darktable an wayland. However, I cannot check how reliable such information is because I don't have enough technical knowledge.

Which way would be the preferable one for darktable? Letting darktable do its own color management (then darktable should somehow be able to tell this to wayland), or leaving color management to wayland? My feeling is that it's the first one, since apparently that's how the Krita devs approached this.

Or is this simply something that's impossible to do in darktable?

I am constantly doing research about this and I am willing to continue if none else does, but for me this seems quite difficult, as a humanist with some very minor coding skills I am not the most qualified person for this.

The easiest workaround that I could think of is letting darktable check if wayland color management is active when it starts, and if yes, switching it temporarily off as long as the darktable window is open. Would this be better than nothing?

No files, tests, or entry points are named. Start by researching the Wayland color management protocol and how darktable's GTK3 and Xwayland usage affects it, while comparing the approaches mentioned for Chrome, Krita, and digiKam. Done would mean a defined implementation path that lets darktable display colors beyond sRGB without disabling system-wide Wayland color management.
