Is it possible to run Vue.js in a Chrome extension?

Question

XSS

Good day!
By default, Chrome extensions have a "Content Security Policy" that prevents templating from working.
It can be mitigated , but it is also written that it is strictly not recommended to do this in order to avoid XSS attacks.
The question is, what is the real threat of easing this policy? Is it a threat to the extension or the user?
ps: I tried webpack+vuefi - it's inconvenient.
