My Insight does that... Why wouldn't Tesla?

Anyway... Plan ahead to not need (much) braking, if possible. True for almost any kind of vehicle.
The problem with blending mechanical and regen braking is that mechanical begins activating just about immediately since it's a direct hydraulic connection to pads that are already slightly touching the rotors. Perhaps there is a way to engineer dead pedal travel in so that it merely sends a signal to activate regen rather than apply hydraulic pressure to the physical brakes. You'd want mechanical to activate at the point exactly beyond the limits of regen though. Very tricky.

My Prius has smooth brake feel up until the point that it transitions to 100% friction braking, which occurs at <7 MPH.

The slight regen from "coasting" is almost nothing, so it doesn't make up for the fact that braking has no regen capability. On EVs without regenerative braking on the brake pedal, I would use the 1-pedal driving mode to capture as much energy when lifting off the throttle as possible.

Of course, as you say, planning to not use the brakes in the first place always applies.
