How should a meta-package handle this note?: 'All declared Imports should be used'

[mauro_lepore]

Following the tidyverse, my meta-package imports some packages only for the purpose of installing them. But the meta-package itself does not use those packages, and I run R CMD Check via rhub::check_on_macos() I get the note All declared Imports should be used.

Should I do anything about it?

> rhub::check_on_macos()

     All declared Imports should be used.

Would https://github.com/mkearney/pkgverse help?

Thanks @maelle,
The answer I was looking for is here:

tidyverse/tidyverse/blob/a720dcd73d9e3fc0ec86317bc0abaf8f0077e8bd/R/tidyverse.R

They are suppressing the note by importing one function from every package, even if that functions is not used.

After that work-around my meta-package passes R CMD check without that note:
