Good point.
Nothing to stop cars that are run-in from using it?
In fact in Australia some used car warranties came with a requirement to treat the engine with a similar treatment as a condition of the warranty?
The debate is often best summarised by a bell chart:

Break-in also takes a while (I'd guess 20 hours of loaded run time is a bare minimum) so it's just not economically feasible to do treatments from factory.
