It's not like this is a default. You're making a conscious choice to
add -j and therefore have to tune what works..

The issue, as I see it, is that the other parallel tasks during the
build are mostly CPU-bound, while this one may very well be I/O bound,
depending on the hardware. You don't want to use only one core of your
laptop for builds, just because its disk can't handle the last step if
done in parallel.

running the compiler, and building the binary sets have completely different
workloads, so I think the parallelism for each should be configured

One can always run in different stages if thats truly an issue for an individual system.

Basically, the knobs already exist but were disabled for everyone...
