Please make -NoTypeInformation the default for Export-CSV
I'm pretty sure that Export-CSV is used for creating Excel compatible files far more often than it is used for Serialising and Deserialising Type-consistent PS Objects.
Alternatively / additionally adding a PS preference variable to set the default behaviour.
I understand that this is simply a convenience thing, eliminating the need to add an extra parameter for the most common use case.
Is not enough for you?
