fordprefect [1] filed a deletion request for python2-radicale [2]:
this is an outdated duplicate (exept it uses python2) of the package radicale. there is no need for a python2-version, since this is not a library, python3 is standard in archlinux and the pkgbuild is easily tweaked to use python2 in the rare case someone really needs it.

While the above is mostly true, this package exists as a transitive dependency for khard, which is python3 incompatible.
This package contains a standalone script, but is also a dependency for others, particularly python2-vdirsyncer, on which khard depends.
i see. is this the reason for the ancient version as well? if so, the flag should be removed and the legacy should reflect in the packages name. otherwise i at least advice to update this.
