Its up to you. If you will have any small issues, preload can block whole
page, even issue is in bottom of page

even if i got a plugin, for preloading, it's not recommended?

No, you can enable only for custom pages. It's not recommended to use it on
all pages.

is there a way to add the preloader to all the pages in the site?
