AFAICS, even libjack only provides functions to start/stop the transport
or get/set the current frame.

Unfortunately, the Jack2 DBUS interface does not seem to export access
to this functionality at all:

https://github.com/jackaudio/jack2/blob/364159f8212393442670b9c3b68b75aa39d98975/dbus/controller_iface_transport.c

You could write your own minimal JACK client to query the transport
frame and check again a few milliseconds later to determine whether the
transport is running.

Using the jacklib.py module included in Cadence (and which I borrowed
for jack-matchmaker[1]), this is very easy to do in Python:
