IIUC the count is only on the number of packages that you import i.e. if 
you import Biostrings, that count for 1.

Note that unlike the Depends relationship, the Imports relationship is 
not transitive. That is, if you import Biostrings and Biostrings imports 
IRanges then you don't get IRanges's namespace in your package's 
namespace, unless you explicitly request it.

We'll see but hopefully it's about direct imports only. Also IIUC this 
is only going to be a NOTE. And we can always step back if things go wrong.

Best,
