Yes, you understood me correctly. Note also that if you specify a
variable, the value of the history variable is modified. When browsing a
history the desire to avoid modifying the history itself is not
unreasonable. This means that in any case you would want to use a
different history variable than the one you are accessing, the history
of your history browsing.

Sure you can do that. You can have a history of your history browsing
and then a history of your history of your history browsing.
All I am proposing is the removal of the unnecessary restriction of
disallowing `t` for the HIST argument of `completing-read`. If you look
at `completing-read-default`, it calls `read-from-minibuffer` directly,
which accepts this. If you use a different completion system, the
situation may be different.
