It's probably still to be avoided but sometimes there is no option is
there? It's also bad to keep stopping and starting engines. Bit like the
old food debate - everything is bad for you but you can't stop eating!

It's a design case for commercial vehicles expected to be used like this. I think that you have to modify the Exhaust Gas Recirculation somewhat to stop it carbonising up too much; but mostly it's a case of "sod it: it's only a company car / lorry / van / JCB". And if they change the oil often enough, and give the engine a good workout from time to time, it probably doesn't matter very much.
Also remember that 1 kW is about 1.4hp, and that when you add in the inefficiencies of generation you probably need about 2hp from the engine to run a 1kW light. So I suspect that they are doing a bit more than just idling if they are running a significant quantity of lights.

I would be interested to see some actual hard facts on the issues. I
cannot believe that leaving your LC idling for quarter of an hour in
the morning is going to create much soot build up if you then run it
normally on a run.
Most commercial equipment is left idling for long periods, but again
that is between periods of heavy usage so again I suspect most buildup
would get blown away.
Having said that a generator is a different story, however it is
generally under load and if tuned properly there shouldn't be that much
soot.
What do you think?
