Indeed, I wouldn't either.

You can set these variables per file:

   https://www.gnu.org/software/emacs/manual/html_node/emacs/Specifying-File-Variables.html

What I usually do, I keep a line:

   # (setq-local org-link-shell-skip-confirm-regexp ".*")
   
With this line, if I need to disable security, I just have to do 'C-x C-e'
at the end of that line.

You may be interested by defining your own link type, so that you can
write, for example:

   [[ssh-L::xxxx:192.168.xxx.xxx:xxxx]]
   
You will not get the security question anymore, and you will have full
control in elisp. That's actually relatively easy to do:
