Should the OLS tag really be a synonym of the least-squares tag?

It seems to me that ols should be distinct from least-squares, since the latter also encompasses total-least-squares.

Tag info:

EDIT: As gung notes, there are also generalized-least-squares and wls (weighted least squares). So their suggestion to reverse the mapping and make least-squares a synonym of ols makes sense to me.
