No one is getting locked out of their files created by an old version. There will be a migration path. The old code will be in git. Worst case, the spec is open

No one is getting locked out of their files created by an old version. There will be a migration path. The old code will be in git. Worst case, the spec is open, I can implement the spec myself in python, using pycryptodome and pyca/cryptography, it wouldn't be hard. I trust his judgement much more than I trust the group that maintains gpg. Of course, actually, there is a community, Filippo is not working in a vacuum. Worst case, if Filippo stops maintaining it or makes bad decisions, someone else (or a group of people) will maintain it.
