WTH - Can't control the "V" in HVAC via Home Assistant?

I have an ecobee and a fresh air ventilation system. ecobee has documentation on controlling the ventilator via their API. Home Assistant has an ecobee integration. But “ventilation” isn’t a common enough part of HVAC to be worthy of HA control? I’m sure there are things here I don’t understand, but this seems like a gaping hole in functionality of climate.
