Hmm, forgot that this is using a shared store currently. So yeah, that
make such a split rather busy work..
I'd then maybe just split UI and API into two separate patches, but not
so hard feelings here.

Yeah, I know that it wasn't possible, but seeing the last state wasn't
either until your patch ;-)
I'm just thinking about what a user might expect to see if there's a
currently running GC operation.

In the UI of the Proxmox VE replication framework there's also a spinner
if there's currently running a log, but if I press the available "Log"
button there, I then get the task-viewer of the current log, which
has its merits. And, FWIW, GC often runs much longer than a
delta-replication.
FWIW, you could always set the UPID and use the availability of the
"last-run-endtime" property as information for if the task is finished
or still running.
