This is a bit sub-Tooty but it needs saying.
There are an AWFUL lot of people in #WordPress who are still happily building with mostly PHP. Many of these are using ACF blocks to circumvent needing to deal with React and complex, fragile build tooling.
I have no evidence (yet) that there’s a mass of people who transitioned to native blocks.
These people are, IMO, a quiet majority who’s keep WordPress at work, but whose needs are often forgotten.
