"Anyone who would letterspace lower case [blackletter] would steal
sheep, said Fred Goudy. There are actually uses for changing the font
transformation matrix / "stretching", "skewing", "shearing" in the
hands of experts - although, as you point out, this property doesn't
actually take a font and "stretch" it with isotropic scaling, but
rather selects a font with the given set width (or, possibly, and this
clearly needs to be clarified as implementations differ, synthesizes 
from an OpenType variation axis or by scaling an existing font).

I can imagine introducing a font-width property that only selects and
never synthesizes, and clarifying that font-stretch can synthesize.

I can also imagine introducing a font-transform property and 
that font-stretch does not synthesize, but that may break some 
content (or the change not be implemented) - e.g. AntennaHouse
Formatter synthesizes.

An example of wanting to transform fonts happens when you're applying 
2d transform but want the individual glyphs to be unaffected, and 
want to (or can't) add additional markup.
