That's correct. Note however that installing a package is not just a thing happening in your R session. It will affect all your future R sessions, and possibly even other users' who have the same .libPaths()[1] {e.g. the group here does share it}. I'd agree to not put a warning but I'd definitely want a message aka "note" to the user. The *wording* of that note should not be alarming at all, I agree, just a note to the user.
