My recommendation is that WP.org stand back and look at the big picture!

Note: I love WP Block themes & all the great work that everyone & the teams have put into them.

WP.org should except and bless, Mike’s Ollie Theme and “Onboarding wizard”.

Mike is a member of the WP team (official or not), I am confident his work will not break WordPress.

Mike’s work should be used as the Model, for WP Core Onboarding.

When WP catches up with Mike’s onboarding … maybe Mike can use Cores Onboarding Framework.
