Hey @joshblack! With caret being deprecated, I wanted to create a PR that removes it entirely (in v38). I'm curious if the best course of action is to wait until v37 is fully shipped, then to open this PR up for reviews/merging?

[joshblack]

Yeah that works @TylerJDev! We did a similar thing for MarkdownEditor this time and I bet it would work for this too

[joshblack]

@TylerJDev for timing on this, would it be helpful to open it when we enter into "pre mode" for v38? Then we could merge it in as-is and go through that route. I think I misspoke earlier when I said open after v37 is merged since this would need to be in the RC for v38 versus being able to land in v37

Makes sense! I'll put this back into draft until then 😄
