Question about block REST API

Hi
Recently we have blocked the REST API for not administrators users (we don´t have users in the site, only a few administrators and don´t use comments).
I found this response https://generatepress.com/forums/topic/restrict-access-to-rest-api-just-like-generatepress-com/#post-690899
and a fewer ones about license or modules activation (that is done for administrators users).
Our aproach is block all request to wp-json in a firewall rule and permit only ip whitelisted, so these request do not reach the server.
So the question is: Have this implications for frontend users?
P.D: I know some plugins need public acces to their REST API end-point and put in place firewall rules to permit these.
