### Confirmation - [x] I can confirm this is a feature request for the Vue component instead of ECharts itself. ### Details Looking at [vue-demi](https://github.com/vueuse/vue-demi), I couldn't help but notice their notice that reads that `vue-demi should not be used for new projects and will be deprecated in the future`. I understand that `vue-echarts` is not a new project, but what about the day `vue-demi` is deprecated? In fact, is there still a need to support Vue 2 going forward?
