OK. I can't think of a case where we would want to represent multiple
DEFAULT placeholders in the context of SET.

Or if we are going to pick up on the recent proposal to allow
column-specific DEFAULT values perhaps we should use a common
representation for the solution here?

In either case, I won't feel stepped on if you implement the solution,
but I can do so if desired.
