Maybe it’s uncommon to have a climate where you need both.
My furnace has a humidistat so in the winter we can adjust how much water gets sent into the hot air stream. But it’s always maxed out because it’s really dry every winter here.
In the summer, the AC takes care of dehumidifying. Running a dedicated dehumidifier would be a waste of electricity, at that point just turn on the AC and any extra cold is a buffer against running the AC later on.
Growing up in Oklahoma, my grandfather ran a humidifier in the winter, and a dehumidifier in the summer. Even with a HVAC system, he’d have to dump out the dehumidifier every other day.
Complexity? You either need a drain, or a supply of water, that can’t be easy to work with, and unlike with a refrigerant loop, you can’t just reverse it to dry/wet things.
Like a humidifier is for me, I’d be so happy to have 40% for a week but it rarely goes under 60
I wonder why there are no humidistats.
You know, a combined humidifier/dehumidifier that keeps a constant humidity.

Mine would need dumping twice a day. I eventually got one with a pump.
Humidifiers are simple and cheap. Maybe the cost of a 2 in 1 wouldn’t make commercial sense.
Also, it would probably need two water tanks, as I imagine you wouldn’t want to use the drain tank as a clean water source.
Just guessing here.
