It probably was... the rationale I think is that high contrast icons are
specially drawn to have thick lines and crisp edges, and that scaling
disrupts those features somewhat. Instead, any small high contrast icons
that are required should be hand-drawn at the small size and provided as
alternatives in the icon theme.  

Low contrast icons, on the other hand, are identical to the regular
icons except for the amount of contrast, so scaling them down isn't
likely to impair a user who needs them any more than it affects the
regular icons for users who don't.

Of course, despite all that advice, the current high contrast icons are
only provided at one size and scaled up or down as needed anyway...
nobody's had time to create the different sizes yet.  (Or to produce SVG
themes from them, which would probably be a better idea).
