Did Drupal CMI do exactly the opposite of what it wanted to do, and create a barrier to entry for teams to adopt Drupal?

Did Config Management Initiative in Drupal do the exact opposite of what it intended to do? Is the lack of a documented Config Management Strategy creating a barrier for teams to adopt Drupal? Can team be successful with using Drupal without investing heavily to figure out their own Config Management Recipe?

Moving this website (tanay.co.in) to Drupal 9

Moved this website (www.tanay.co.in) from an older version of Drupal 7 to Drupal 9. And switched the DNS to this new site, just a while earlier.

The migration was fairly straight forward using the Migrate Drupal UI module. I had attempted moving this site to D8 5 years ago. It was a bit messy, and I chose to leave it in Drupal 7. My observations from back then are detailed here.
