The same is not true for alkalis.

The manufacturers data sheet seems to disagree with you. The voltage
drop is reasonably linear over service life. What could give a better
indication of remaining charge? It just requires a slightly different
sensing method.

Those graphs are for a highly artificial case of a constant discharge.

You'll probably find quite a variation in the voltage of a cell with, say,
50% of it's energy left depending on how quickly it was discharged to that
point.
