FYI, you are mistaken that C code is always "source". C is sometimes
generated from other forms, via transpilers or lexer generators etc.
It can also be obfuscated C code from the real C source (cf #383465).
Likewise for HTML, it is often generated from templates or simple text
languages like markdown.
So like C, OTF can be source or not source, depending on the upstream project.
C to ELF is not a one-way process, there are disassemblers and decompilers.
Likewise for HTML and PDF. LibreOffice and other software can even edit PDF.
Likewise, the conversion from Glyphs to OTF definitely throws away
information. Even the conversion from Glyphsapp to UFO format (which
is sometimes used as a font source format) throws away information
according to the Glyphsapp documentation:

That would be a disingenuous workaround for the choices that Firacode
upstream has made and the reality of the Free Software ecosystem for
fonts in 2017. If you convinced Firacode upstream to switch their
source format then that would be different. Or if FontForge or
FontTools or another piece of Free Software started to support
Glyphsapp format, then their choice would be fine for main.
I have a better thought experiment:
Would Debian put a free Java program in main or contrib in the time
when the official JDK was proprietary and GCJ hadn't been implemented

It is unfortunate that the gsfonts upstream didn't ask the right
questions before integrating these files into the project. They really
should have done that. At that point in time we would have to remove
the URW++ fonts from Debian since we would not be in compliance with
