I think it should work, but I haven’t tried it either.
Though there is a difference, the article says:
If you take this to its logical conclusion, you realize that, if you provide an Assembly for every platform in the PCL, this means that nobody will ever execute the code in the PCL version, only the platform versions.
The difference is that there is no fixed list of platforms that support a certain version of .Net Standard. A platform can appear tomorrow that supports the version of .Net Standard you chose and that you couldn’t have known about when you wrote your library, so you couldn’t have provided a separate assembly for that platform.
