Youre right, its a different target market.
Also I stand corrected, I was looking at the issues in the wrong way. I read this article and have been meaning to circle back to this comment .

TL'DR: SVGs are security issue for hosts, so they are not widely hosted the same way PNG's, JPGs, and GIF's are.
Instead you can host the SVG in a block contained in HTML, like so on SquareSpace. The blocks are limited on squarespace though because code blocks do not support XML, the language that SMIL's is based in.
Also to clarify, SMIL = the language used to code SVGs, full index here: https://www.w3.org/TR/SMIL3/
So if you use a Squarespace code block you have to your SVG it into HTML using <SVG></SVG>.
Hosting it on GitHub as a GIST is better though, in my opinion. Its cleaner to link the SVG image in rather than have the code plopped into a box anyways. That way you can contain the entire SVG in a file ending in .SVG, using SMIL (pronounced "smile" 🙂 )
If you want to know how, follow the article to upload your SVG to GitHub as a Gist, then you can just use either CSS or HTML to link in the SVG as in image
Also @creedon you're right, this isn't really a necessary feature for their target use / demographic
