This issue is just to clarify if devtools needs to work or not in prod. mode.

Questions that we need to awnser:

• Why disable devtools in prod. mode?
• Today we can disable in prod. mode but there is a bypass with a single variable, this means that the API of devtools is loaded every time, is this correct?

Vue3 change the devtools logic flow, look for this comment #1308 (comment)

Summary

Vue2 have this problem, Vue3 have no problem. And I also don't know why we need disbale devtools in production, React didn't do it but nothing happened.

Today we can disable in prod. mode but there is a bypass with a single variable, this means that the API of devtools is loaded every time, is this correct?

   var devtools = inBrowser && window.__VUE_DEVTOOLS_GLOBAL_HOOK__;

  if (devtools) { ***

me: If user don't install vue-devtools, this check will failed, don't need worry it。If you care about security just remember Frontend code is untrustworthy , Backend need do strictly auth check
