Thanks for the contribution! We're going to pass on this one though — the regex approach is a bit fragile since it won't handle cases like nested braces (e.g., estimatedListSize={{ height: 100, width: 200 }}) or multi-line prop values, and we'd rather not add something to the migration guide that might give users a false sense of completeness. The list of deprecated props is short enough that removing them manually is straightforward. Appreciate you thinking about ways to make the migration easier!
