        Having run tracer after a system update how do I determine

    You should restart:

         DiscoverNotifier
         Isolated Web Co
         Privileged Cont
         RDD Process
         Socket Process
         Utility Process
         Web Content
         WebExtensions


Does:

# tracer --helpers

... make things clearer? Or, for example

# tracer -s 'Privileged Cont'

Always check the --help for a command and/or its man page.

Issuing tracer -s 'Utility Process' now tells me that application 
Utility Process is not running, so how do I determine what it was?

If it's not running, why does it matter? (almost certainly it's a
worker process under Firefox)

Also having just done an update now tracer tells me that goa-daemon and 
plasmashell should be manually restarted. Tracer -s goa-daemon tells me 
it is package gnome-online-accounts, and from its name I'm assuming it 
can be restarted via systemctl, but as I'm using KDE I can potentially 
ignore the restart suggestion, would that be correct?

No, because you may be running some Gnome (or GTK) app under KDE, which
is why tracer detected goa-daemon. However the man page for goa-daemon
says that it starts automatically on demand, so there's no harm in just
killing it, e.g., with pkill. 

With the suggestion to manually restart plasmashell how do I do that 
without shutting the system down or is the KDE environment not running 
under Plasmashell?

I have a tiny script for that, thanks to Rex Dieter:

   $ cat bin/replasma 
   #!/bin/sh
   
   # KDE list 06/01/2019 Rex Dieter <rdieter@gmail.com>
   
   systemctl restart --user plasma-plasmashell
   $
