This is a big change for many of the community written and supported tools. It is unreasonable to have them be unable to take on new users until they are rewritten, which could take several months given that these are volunteer efforts. You should:
- Defer these changes by 6 months, providing time for rewrites to occur
- Pin this post in the announcement and developer categories here, and
- Post this info on the developer portal and the PAT generation pages. I just looked and this info does not seem to be there.
Deprecation of PATs as a persistent permission mechanism is a big deal. Perhaps not as big as the shift to Edge drivers, but still non-trivial. Samsung needs to respect the developer community and provide an adequate timeframe for this transition, with a lot of communication and information along the way.
