Comment (by dmsnell):

 @leec87 and @Chouby — the new `WP_Block_Processor` class introduced in
 #61401 includes a method named `$processor->is_non_whitespace_html()`. The
 class is designed to efficiently scan through blocks in a post and make
 textual edits easier, and this method can be used to differentiate top-
 level freeform content which contains “real” content from those containing
 newlines and spaces, according to the prettified serialization.

 Hopefully that makes some of what you are doing easier. By default, the
 class skips top-level freeform content, hopefully removing some of the
 surprise.
