I'm generally seeing ~1sec increase in boot time for 1 and practically
no difference for 2 (even after having added patches that provide
runtime performance improvements).

One second is considerable IMO. Aside from the general desire to have
shorter boot times on any platform there are environments like
automotive where boot time is critical.

Yeah, definitely.  Is this actually blocking boot and if so can we
arrange to do this in parallel with other activity (with likely knock on
effects on reproducibility...)?

No, this goes in parallel. That's also showed by the fact that the
benchmarking thing itself usually takes more that 1 sec, but it seems to
impact for that amount of time only.
