No, I don't mean a new environment variable, I mean a new DBusBusType
(and the GDBus, QtDBus, etc. equivalents) alongside DBUS_BUS_SESSION
(and the GDBus, QtDBus, etc. equivalents).

The system bus certainly needs a new DBusBusType anyway, because in
general things that connect to DBUS_BUS_SYSTEM expect dbus-daemon to
enforce their security policies from /etc/dbus-1/system.d.

I initially thought the session bus didn't necessarily need this,
because in practice /etc/dbus-1/session.d isn't used; but if
compatibility with other aspects of kdbus semantics is a concern, then a
new thing alongside DBUS_BUS_SESSION as a way to opt-in to kdbus
semantics might be a necessary evil.
