 There are a few references to Gutenberg specific functions or named with
 the `gutenberg_` prefix that should be updated in Core.

 - The `render_block_core_legacy_widget()` function has calls to
 `gutenberg_get_widget_key()` and `gutenberg_get_widget_object()`
 ([https://core.trac.wordpress.org/browser/trunk/src/wp-includes/blocks
 /legacy-widget.php?rev=51351#L32 source]). It seems that this entire
 conditional block can be removed in favor of the first condition's code
 since WordPress >= 5.8 can be confident the methods exist.
 - In `wp-includes/blocks/post-template.php`, there is a function named
 `gutenberg_register_legacy_query_loop_block()`. The docblock says that it
 "can be removed when WordPress 5.9 is released" and appears to unregister
 the `core/query-loop` block before re-registering it. Is there any reason
 why Core can't authoritatively register the block type as it does others?
 ([https://core.trac.wordpress.org/browser/trunk/src/wp-includes/blocks
 /post-template.php?rev=51351#L112 source]).
