Comment:

 I've been doing some more investigation here today, and this is a lot more
 involved than I anticipated.

 It seems that the older themes that had block patterns added this release
 cycle in [51012,51033,51043,51045,51103,51106] all produce block
 validation errors in WordPress 5.5, even after reverting [51372]. This
 means the initial block patterns introduced do not work on WP 5.5.

 WordPress 5.6 has more mixed results. For example, Twenty Twenty-One has
 no issues after [51372]. I have not tested Twenty Fifteen and earlier yet,
 but Twenty Twenty through Twenty Sixteen all have validation errors after
 [51372] but did not before.

 I have not yet tested WordPress 5.7.

 With this in mind, I am tempted to revert [51372] in `trunk` in favor of
 exploring a better solution that provides better backwards compatibility
 and aiming to release a new version of default themes shortly after 5.8 to
 address these issues.

 @ryelle what do you think?
