LR3 had both an exposure slider and a brightness slider. The exposure slider in LR4 is essentially the same as the one in LR3. They made many changes to the brightness slider in LR3 and called a new LR4 slider highlights. The exposure slider moves the entire tone curve. The brightness and highlight sliders control the right portion.

Given the history, it would be confusing to call the exposure slider "brightness adjustment".

Do you believe anyone is confused by a slider called exposure (or, at least, anyone who is not being willful)?

IMO, the most logical thing would be to have a slider called "gain" which would be a purely linear treatment of the RAW data, and along with that controls for contrast, shoulder, knee, etc, for the rendered tone curve.  Most converters don't even give a homogenous gain with the "exposure" slider; the curve changes along with the gain.
