@jenskutilek@typo.social, in 2019 you mentioned in https://github.com/IBM/plex/issues/206#issuecomment-458465851 that you had written a Python implementation of FontLab-style TTH compiler and said you weren't against releasing it. I'm wondering if this could still happen. I have a font which was created and hinted in FontLab 5 (I guess? Its source files were in vfb format). I could probably make some real use of your compiler if it were available.
