I was really excited for Vue3 and constantly being told at the Austin VueConf that it will be backwards compatible. But reality was very very different.
There are a bunch of breaking changes to Vue 3 that will require code changes, and whilst the vue compat package is meant to alleviate some of that it was only released as of v3.1 and still does not handle all the breaking changes.
Some of these breaking changes also seem like they could have been been a good addition and not a full breaking change. Consider the v-model changes, why change the underlying events? You could have it work both the old and new way and log a deprecation warning for the old way. Give engineers more time to fix the code as they see these issues with out breaking.
Probably the biggest pain point I have hit with moving to v3 is the state of vue-test-utils, it is still in RC. Honestly I would have loved to seen this released in lock step with Vue, I mean it really should if it is how you are meant to unit test your components.
That being said obviously a lot of my pain is coming from v2 to v3 I imagine being green field the experience would be fantastic. I still really love using Vue just the upgrade has left a bit of a sour taste in my mouth.
Vue 3 has definitely been a terrible launch for such a large framework. Many of the official supporting libraries are out of sync, the devtools don't work and require a manual beta install, and other projects like nuxt.js seem to be in a perpetual delay. It's unfortunate as Vue was known for having a strong lead and consistent releases but it's too much of a mess right now.
Sadly remembers me a lot of python 2 to 3 transition. Some companies never upgraded, and never will (left one because of this, among other things). Some others facing such a big and difficult change took it s step forward and moved to slowly transition to other languages. Hope this isn't as bad, but looks too similar to me.
