Ionicons v4 with Ionic v3

Anyone did try to upgrade the ionicons to the new version v4 while still using Ionic v3?
Everything went fine? Is that possible?

Well so if I understand the comments on the blog post https://blog.ionicframework.com/announcing-ionicons-v4/

It doesn’t make that much sense since ion-icon is part of ionic-angular therefore the “old” icons would be still shipped with the app even if not displayed

Kind of the same question and a Stackblitz to try out: https://forum.ionicframework.com/t/ionicons-v4-custom-svg-with-src

I close this, I think it’s not straight forward possible and doesn’t make that much sense since you would have to find a way to remove the v3 icons in order to not make your app to heavy
