Thank you for supplying the tangent on font sizes. I've been just searching for a recommended standard for size naming conventions over the past few days and was happy to see this referenced in this post.

I can already see that referencing font size names like "Gargantuan," and "Colossal" let alone "Titanic," "Olympic," "Planetary," etc. with clients will sound fairly amateurish while also still not providing a clear hierarchy of sizes. This will only be increased when building for a non-English-speaking (or English as a primary language) audience.

In looking through comments like https://github.com/WordPress/gutenberg/issues/29568#issuecomment-913153681, do you see a problem in using an approach like overclokk's:

--wp--preset--font-size--base // where m size could be the base font
--wp--preset--font-size--xxs
--wp--preset--font-size--xs
--wp--preset--font-size--s
--wp--preset--font-size--m
--wp--preset--font-size--l
--wp--preset--font-size--xl
--wp--preset--font-size--xxl
