I am not sure this is (still) correct - I am able to call into a .NET framework 4.8 library from .NET 7.

If it's built against .NET 4.8 but only uses the API surface subset that corresponds to .NET Standard, that works - but then it's effectively a .NET Standard library with metadata not properly reflecting that.
Since .NET Fx 4.7 or 4.8 libraries consumed via NuGet are "assumed" .NET Standard 2.0 unless proven otherwise for maximal compatibility with old code.
