I don't think this is a good advice in general and I haven't seen many companies to do it practice. The initial decisions which a company makes most of the time are hard to change. Moving a successful business with clients from one platform to another 3 or 4 times is very difficult to do or hardly impossible.

It may work for a simple website, but for any more complicated project with web clients, mobile clients third party integrations, migrating from Heroku to cloud provider to on prem means refactoring big parts of the project.

What is even bigger problem a migration like this is hard to do incrementally.
