wp_body_open and //phpcs:ignore notation

hello kind GP ppl,

is the comment //phpcs:ignore is specifically for Theme Check purposes, best practices, or simply a coding courtesy? i see it a lot in GP.

i read about wp_body_open here:

wp_body_open

generatewp.com

wp 5.2 update

i’m as of yet unfamiliar with php codesniffer.

to my self-trained eye, the GP implementation of wp_body_open is an alternative backwards compat w added benefit of using less code.

if there’s a better place to submit non-support Qs and comments, please advise. i don’t want to be an annoyance, but i really enjoy learning about programming, php and WP using GP theme.

thank you, L
