If you create a .csproj that gets this GUID F# Project Type, and try and load the project on an IDE that does not have support for that project type you get an unsupported project type error, of course.
I'm not sure if there's a way to only add this GUID if there's any f# content actually in the project or not, but that would be ideal, otherwise I feel I need to toggle those add-ins on or off when creating projects intentionally with F# support in them.
