I enjoy Relentess Refactoring as much as the next guy, but one dimension here is that it is much easier to do in a headless app (or in the backend) than in an app with a major UI. At some point there must be a complete switch from the old UI to the new UI, and that step is extremely complex. It also invites a big rewrite, in an almost irresistible way - "since we'll change the UI, let's just do it from the ground up".

The main lesson of the CI/CD era is that pain is information and ignoring it until later just makes things worse.

"Let's replace the whole UI at once" and "Let's replace the whole app at once" are bandaid-ripping activities, and the point of ripping off a bandaid is to get it over with before your pain receptors have a chance to tell you what an asshole you are right now. I'm sure most people have at least one experience, of their own or of someone they know, where ripping off the bandaid took a chunk of skin with it, possibly creating a bigger wound than the bandage originally covered.
