For the "tweaking the output part", it looks this is already possible on
the user's end via org-columns-modify-value-for-display-function.
Here's a lightly tested function that I think does what you want:
(defun my/org-columns-remove-brackets (_title value)
(and (string-match org-ts-regexp value)
(match-string 1 value)))
(setq org-columns-modify-value-for-display-function
#'my/org-columns-remove-brackets)
