Should params arrays be declared nullable?

[Keboo]

There a few cases to consider here (assume nullability enabled):
Array that contain nullable types (object?), value types (int), and non-null reference types (object)

Should there be guidance on if the params array be declared nullable?

Proposal:
CONSIDER: Declare params arrays as non-nullable.

This aligns with built-in methods such as string.Format.

After discussion, this is unlikely to provide much value. Though good to declare non-nullable the impact is low and the value add is also low.
