Another thing to take into account is if the block is static or dynamic or, more specifically, if it will load JS assets only in the admin, or in both the frontend and the admin. If it is a static block, simply saving its HTML in the post content and not loading any JavaScript, then even if we install 300 of these blocks, it doesn’t really matter because the bloat is restricted to the admin side, so people browsing the website are not affected (also CSS, but it’s not as bad as JS bloat). And disabling these blocks at a later stage, once the user finds out about the bloat, will not break the website either, so it is kind of safe. Main problem is dynamic blocks, since these could break the site when disabled.
