So if your scenario requires both a NuGet-compatible semver v1 value for Chocolatey and a semver 2.0 version stamp on your actual NuGet package, NB.GV 2.3 is going to create problems for you unless we somehow fill that gap.
This is exactly my scenario as Chocolatey requires NuGet SemVer 1 compatible versions and gets tripped up by tags that start with a number. In my project, I build a nuget package and a chocolatey package and I'd like to use SemVer 2 for NuGet while having a "nuget semver 1" string available for chocolatey.
