Hi devs, I found there are over 800 @Deprecated in the project, and most of them have the comment 'to be removed before 2.0'.
So do we have a schedule or plan to remove them?
You can use GREP to quickly check deprecated annotations.
```
> grep -roh "@Deprecated" . | wc -l
802
> grep -roh "@Deprecated // to be removed before 2.0" . | wc -l
731
```
