In what way ?
In other words, you'll have to much better define what you
mean be "deleting a value".
DROP COLUMN already exists, for that matter.
Updating a column to its DEFAULT value may also be closer to
what you envision a "column-delete" to do.

Agreed, this is a much better approach to achieve the same.
I am a bit skeptical about whether the proposed syntax will be
acceptable if it's not SQL standard, unless it's absolutely necessary
to support functionality that can't be achieved with the existing
syntax which is not the case here.
