It's a somewhat difficult issue and I understand being hesitant because of this. Converting to SVG is one possible path around it which isn't too bad but having it natively is of course even better.

The thing is, inserting PDF for just the PDF export would be quite easy. The issue is the other export targets Typst supports (SVG and PNG) as that would require some form of rasterization / a full blown PDF engine written in Rust without C-bindings because of the web app and that simply does not exist yet.

And the developers are hesitant to just add features for one specific export target which I get.

I thought about trying it. This just killed it for me...
