Maybe I'm missing something, but doesn't it do this already?

"The length of record component pattern list must be the same as the length of the record component list in the declaration of the record class named by ReferenceType; otherwise a compile-time error occurs." (14.30.1)

It would be one thing if you want runtime checks, but you're just saying you want a compiler error, right?
