Looks like I sloppily considered Metatype and Metatype1 the same
project.  The download README is from 2009, and there have been a number
of fonts produced using it.

The Polish TeX programmer team is continuing to create fonts using this
tool as far as I know, though few others have picked it up.

The TeX Gyre project
<URL:> uses
it according to its documentation, and works with roundtrips from
outline PostScript fonts to Metatype1, editing and supplementing
(diacritics, for one thing) and going back to Type1.
