Are you suggesting the code that is written to enhance data integrity is optimised (or even touched) to support this kind of test scenario?
Seriously? :)

also, when a rebuild is slow enough (and has enough of a performance impact) it's not uncommon to want to operate in degraded mode just long enought oget to a maintinance window and then recreate the array and reload from backup.

so would mdadm --remove the rebuilding disk help?
