Comment (by hellofromTonya):

 What features will use this API in 6.2?
 What existing blocks already in Core (ie from before 6.2) will change to
 use the API?

 I ask for these reasons:

 * Performance analysis.
 I asked @flixos90 to review for performance. Knowing which features will
 use it provides needed information for testing before and after for
 existing blocks (i.e. blocks already in Core).

 I'm curious and concerned about the potential introduction of performance
 regressions. Why? There's a lot of code to execute vs the PHP native regex
 and string functions. The way to remove those concerns to do a performance
 review to collect data.

 * Testing.
 Test the usage to validate the API works as expected.

 * Assessing risks to users.
 For existing blocks (in <= WP 6.1.x) that will change to use this API,
 want to test  before (6.1.x version) as compared to 6.2 version. Why?
 Confidence check to identify any markup changes or potential breakages for
 users upgrading to 6.2.
