Is my understanding correct this will actually significantly impact F-Droid since it enforces install limits on duplicate package IDs with differing signing keys that are registered after the first?
So basically only apps that the original developer registers and is using reproducible builds are fine.
And the apps that use a unique package ID for F-Droid.org are also maybe fine if they allow F-Droid to be a validator, which is probably unlikely.
The remaining 85% are basically guaranteed to get stuck in limbo?
