I --stop(ped) an array but /sys/block/md2 remained largely populated.
Is that intentional?

It is expected.
Because of the way that md devices are created (just open the
device-special file), it is very hard to make them disappear in a
race-free manner.  I tried once and failed.  It is probably getting
close to trying again, but as you say: it isn't a high priority issue.
