Just out of curiosity is this still technically possible?
Depends on what "this" is referring to.
For all practical means, all the strats are out of reach of any GV for the most part since the redesign of the strat system, as no GV spawns are leading to them anymore. And so is the HQ, as on the few maps where a VBase is spawning to a HQ, the base itself is uncapturable. Also one Ostwind would not be enough to kill HQ anymore, and neither is an Ostwind or Wirbelwind capable of killing a town on it's own.
