Ack! I used to have 3-handle controls and loved them; our new (built
2000) house has a single round control. Given similar pressure on the
water line, it lets less water through to the shower head, and the one
we have doesn't even give flow control. It's either on or off, you just
get to choose the temp by rotating it.

You can still find single control faucets with a lever instead of a round
knob. That gives you much finer control over water volume.
