They are not back and likely will not be. You can still create units to support you in building, mining or healing units, but you can now play as them and control multiple at once, some have health regeneration and very fast build speed. You can also build offensive units of course, and also play as them.

i always thought upgrade pads were not as convenient as unit factories because you absolutely have to go back the the upgrade pad but if you are setting up defenses near the drop zone and have quasars or pulsars they will walk right up to the spawn
