That's not overwriting. org-columns-modify-value-for-display-function is
not a function, but a custom variable defaulting to nil. You have all
rights to set it to whatever you wish.

Hmm. You are right. This should be a bug. It happens because
org-colview.el is only loaded after you actually run column view or
corresponding dblock. Before that, Emacs is not aware about this
variable (unless you require org-colview manually in your config).

That's probably because the function I provided tries to compute the
description part of the link by querying the headline for each result.
You may get much better performance using the following version:
(defun yant/org-columns-custom-formatter (column-title value)
"Format column values for columns with ID-LINK title as proper Org mode id: link."
(pcase column-title
("ID-LINK"
(format "[[id:%s]]" value))
(_ nil)))
Best,
Ihor
