The package offlineimap will go sooner or later since Python 2 is EOL.
The migration from Py2 to Py3 is not clear [1] and the README [2] says:

IMHO, the transformation is the easiest to still have the package and
let the time to switch (to Offlinemap or something else).  For instance,

<https://github.com/OfflineIMAP/offlineimap3>

Note the package should always be available via inferiors.

All the best,
