Well the very first step would be: native R support for installing specific package versions, and sharing that with others. There’s too many third party solutions that come and go over the years. And there’s no guarantee that what you select today will be understood, or work, tomorrow.

There is `renv` for that

Which is a third party solution. A few years ago you may have said packrat. A few years from now you may say some other thing.

The idea behind a native R solution is that it is far less likely to be deprecated.
