From the quality requirements:

New fonts may be accepted if they provide value beyond aesthetics (e.g. they contain glyphs for a script missing in already packaged fonts).

What's your argument in favor of this font? (Code ligatures fall in the "aesthetics" category.)

[gbrlsnchs]

It's a pretty popular programming font. I am basing my argument mostly on GitHub stars. Also, it's made by JetBrains, making it even more popular and well maintained.

[ahesford]

Fonts can be installed per-user by copying into ~/.fonts with the default configuration.

Sure, no problem. Thanks for reviewing.
