Since DxcBox is going to be deprecated, and DxcCard and DxcTag use DxcBox inside, should we deprecate also DxcCard and DxcTag? @GomezIvann

I don't think so. When we remove the box we just have to change their implementation. And luckily, they both are components that are going to be redesigned soon (I hope so). Do you agree?

Totally agree. They will be redesigned and reimplemented soon 🤞🏻.
