Thanks, this sounds clever and I think I understand the code.
Although I would have preferred not to overwrite a function. I
always have a fear that this leads to nasty side-effects with future

Without deeper knowledge, I was astonished that C-h f
org-columns-modify-value-for-display-function did not lead to a
matching function and C-h v ... to a matching variable.

However, I set up following test file and it worked:

    #+BEGIN: columnview :id global :match "+project+focus/!+STARTED|+NEXT|+WAITING" :format "%TODO(State) %ITEM(What) %ID(ID-LINK) %TAGS(Tags)"
    | State | What           | ID-LINK        | Tags            |
    | NEXT  | [/] focus proj | [[id:2021-07-27-focus-proj][[/] focus proj]] | :focus:project: |
    * Test
    ** NEXT [/] focus proj                                                               :focus:project:
    :CREATED:  [2021-07-27 Tue 13:59]
    :COOKIE_DATA: todo recursive
    :ID:       2021-07-27-focus-proj
    ** NEXT [/] non-focus proj                                                                          :project:
    :CREATED:  [2021-07-27 Tue 13:59]
    :COOKIE_DATA: todo recursive
    :ID:       2021-07-27-non-focus-proj

When I applied the new change to update a table in a file of 71k
lines of org, I had to cancel the process after over two hours
without a result. Before the change, updating this table took
roughly 20 minutes.

Therefore, this somehow makes a poor performance even worse.
