.woff2 version

[o-t-w]

Is there a .woff2 version you could include in the download? I know there are tools I could use to convert it but some of those are not compatible with variable color fonts afaik.

I don't think so. What do you mean by that? woff2 compressors (e.g. the c++ one from google/woff2 repo, or the fonttools ttLib.woff2 compress script in the python FontTools library) do not care whether the font contains variation tables or has COLR or SVG or any other color tables.

Last time I checked the webfont generator at FontSquirrel messes them up.

maybe they are dropping tables they don't know about, I have no idea how that works, but the mere act of woff2-compressing a font does not involve dealing with variable or color tables at all.
I suggest you try using woff2_compress command line tool directly https://github.com/google/woff2

I wonder why the download from Google Fonts doesn't include .woff2.

I just checked, and FontSquirrel indeed drops the COLR/CPAL tables.
