I'm not sure why there is a pdf. The pdf seems to contain the rasterized logo again, so no vectors. What is the purpose of the pdf?
Including the odg file is nice. This is for later editing I think? My browser (and OS) don't know what to do with such a file though. So if your plan was to include a vector graphics file that can be used as an alternative to the png, I would suggest adding it a SVG instead.

Also, the logo is added to the repo, but it hasn't been added to any documents, such as the readme. Is that deliberately left for later?

Thanks. The pdf and original formats are replaced with svg.

yes, the logo can be used later.
