There's also Neatroff by Ali Gholami Rudi.  It has TeX's paragraph
formatting and several other new features, taking from Plan 9,
Heirloom, and Groff.  IIRC, it's an implementation from scratch.
https://litcave.rudi.ir links to its introductary PDF in the first
paragraph, https://litcave.rudi.ir/neatroff.pdf, and a Typesetting
section below the change-log.
