Sure it could.  It's just a matter of uncommenting a line in
the source code.

		//atsuLayout -> SetTransientFontMatching ( true ) ;

The reason why this line is currently commented out is that
enabling font substitution negately affects performance,
especially when reflowing a layout.  I probably need to
introduce a new feature flag to let the client enable or
disable this functionality, just like MLTE does.

This "switchback" behavior is actually a side effect of the ATSUI
implementation of font substitution: the font doesn't really switch
back because it was never really changed in the ATSUStyle object.

Yes, the caret could be made to appear as a traditional one-pixel wide,
solid line, by slightly nudging the origin of the caret rectangle.

But it may look anti-aliased (blurry) again if you change the
transformation matrix (perhaps to zoom the text), or if you image
the text onto a different target device, or if caret slanting is
enabled for italic text.  This is a natural consequence of using
Core Graphics for all imaging.
