I already have a derivation for ptvsd in NUR (the original project). I will see if I can adapt it for debugpy.

@leungbk Sorry that this is taking so long. I spent quite a bit of time trying to get the tests to pass; now everything builds & passes successfully, but I'm having troubles using it with dap-mode in Emacs.

If you want to try it out, I have it available in my NUR repo.

@MetaDark Thanks a lot! The cli seems to work for me as well.

In Emacs, I seem to get something with the following changes to dap-mode:

Every other adapter uses launch locally, so this is probably not right. Vimspector seems to use launch for local debugging (https://github.com/puremourning/vimspector#python) and attach for remote debugging. I haven't inspected the source or tests of either Vimspector or debugpy very carefully. I'll take a closer look within the next few days.

It would be great if you could submit your derivation upstream here.

@leungbk Thanks! Using "attach" instead of "launch" was the missing piece. It seems to work well after a bit of testing, so I will submit my derivation.
