Sorry, no part of your comment is true. This is easily the best option for slow connection/device users, and it comes at the expense of the design.

Nope. Slow connections' floor for first paint is 100ms when using `font-display: optional` – not an additional 100ms. The page is still loading like normal in this period. (If you're already under a 100ms FCP for 3G users, you know all of this already)
> the content will jump by some large amount
`font-display: optional` is literally designed to prevent this from ever occurring. Either the font is ready for first paint in 100ms, or another font is used.
