Is it worth changing ViewModelBase.RaisePropertyChanged to use the CallerMemberName attribute?

If you look at the Portable.MvvvmLightLibs fork (matches the 4.1.26 official version), it currently does use the CallerMemberName attribute.

That version supports portable class libraries, windows phone 7.5 & 8, SL4+, and .net 4.5 and store apps.
