That’s exactly what I’m using this for: 2*2L liquid storage on a 50kg 2-tile forest/tight spaces cargo motorbike for almost no additional weight.
Indeed, I will not use a proprietary platform (GitHub) for development of free software. I consider it unethical. My patches are in ‘git format-patch’ format, which makes them easily integrated using ‘git am’ for whoever wishes to do so (and then you might git push it all somewhere and click proprietary buttons).
