Because it works instantly with one click and unblocks everything immediately. The danger is getting used to it and never switching to a proper fix, which leaves you thinking your app works when it does not for real users.
Because it routes the request through a server-side origin, works reliably across your team, mirrors how production works, and does not rely on disabling a security feature. It teaches you the real fix.
Only for one-off testing when you want to see a response quickly. Remove or disable it afterward so you do not fool yourself into thinking your app works when it does not without the extension.
