Well only to a point, I don't think there's been any significant or formal "we spell this existing word like this now" in a very long time.

The only way English language really evolves now is by the addition / invention / adoption of a new word or added meaning to existing words, like yeet, influencer, youtuber, incel, looksmaxxer and simp. And a lot of them are meme words not actually used in normal parlance. Others are the wider adoption of subculture specific words and expressions, like AAVE getting adopted by teenagers / young adults.
