So essentially, all clients have to keep implementing the old
VT_SETMODE interface in addition to the new logind one?

Would it be possible to ship a wrapper around VT_SETMODE and friends
so that new clients could only implement the logind interface, and
logind would deal with the VT layer internally (or rather, I suppose,
via some shim session daemon) when necessary?
