Earlier quoted context omitted.
I just switched from MacPass to KeePassXC for the reason mentioned in release notes: it obsoletes the HTTP Connector and uses another mechanism. MacPass keeps using HTTP, and it is uknown, when it will do the same switch. Given that I use multiple computers, and the extensions are synced, I want to use the same mechanism on all of them.
Do you know the details of the differences between the old and the new mechanisms? All I see is a migration is required, but I used neither.
