I celebrated the anniversary of the (internal) bug asking for SVG support in Google slides. I think it's up to 15 years now?
So, uh, don't get your hopes up.
Well SVGs I understand being harder to support, those aren't really images. And various anti-injection security rules treat it as untrusted HTML code.
There is a workaround for using SVG in Google Slides by using Google Drive to convert to EMF (a format I’ve never heard of anywhere else). It’s a pain, though.
It seems so strange to me that it is this hard to add: I wrote a userscript recently to extract titles from slides and if I recall Google slides already renders in an svg format. Wondering what's going on here.
