Comment (by exstheme):

 Hello, dear @costdev !

 Thank you very much for this commit:
 https://github.com/WordPress/wordpress-
 develop/pull/2175/commits/daeade936c57fb00824be4c954cf2bbd2ee2f75b
 It is exactly what we're looking for:

 1. Now even if file '`templates/index.html`' exists we're able to disable
 'block theme' functionality with this filter:
 {{{add_filter( 'is_block_theme', '__return_false' );}}}

 2. Now the only source of truth to check if theme is a block theme is this
 method:
 {{{wp_get_theme()->is_block_theme()}}}
 which is great!

 So now if user wants to just check new FSE feature it can just check the
 appropriate settings checkbox. And if he decide to switch back - he can
 uncheck  this setting.


 Dear @poena !

 I guess that adding ability to easily convert classic theme to a block
 theme and back is a good opportunity to let users to check and experiment
 with the new FSE feature with their theme of choice. And if anything will
 be broken they can always switch back without changing their theme.

 And for theme's authors it is a great ability to update their existing
 themes without creating, supporting and maintaining new ones.

 Hope this make sense for you.

 Many thanks to everyone once again for your quick actions!
 Best regards!
