Comment (by joemcgill):

 @spacedmonkey and @thekt12, this function is still being used in
 `_get_block_templates_files()` ([https://github.com/WordPress/wordpress-
 develop/blob/58d47f5c809410dd0ed3279f41b1bf2d006ea53d/src/wp-includes
 /block-template-utils.php#L336 reference]).

 In a recent profiling run I conducted, I can see it getting called 3 times
 during a pageload, and while the parent function
 (`_get_block_templates_files()` has a significant impact on server
 performance, `_get_block_template_paths()` doesn't seem to have much
 impact at all, so I think it's fine to deprioritize this.
