When I unplug that drive, /dev/sda is removed, hotplug seems to work to

Replugging shows the drive re-appearing as /dev/sde

It seems hot unplug does not remove a drive from an md array.

Is this intentional?

Yes. You may want to re-add it to the array (see man mdadm (new-ish)
for --re-add with bitmaps). Your userspace should probably take care
of removing the failed device.
