Footnotes on sidebars are good for most simple cases but insufficient for more elaborate structures, but you can in fact put a footnote in a footnote to get more than one indentation level.
I like the idea of footnotes on footnotes. I can see an interesting exploration in this space where footnotes (and footnotes of footnotes) appear as a bottom bar/appearing over the text. Sidebars don’t work IMO as on smaller screens there is not enough horizontal space, and mobile is where a lot of text is read.
