Could I create custom `useCustom()`?

[thearabbit]

For example I base on Meteor + Vue.
I use vue-meteor-tracker (https://github.com/meteor-vue/vue-meteor-tracker)

I would like to create useCustom for this???

I think you can specially create a repo to implement vue-meteor-tracker with composition-api, if use store or router, you can depend on this repo.
