This is basically what we have now - conform to "current" system time
zone. We are not going to remove this timestamp style. Just add an
ability to explicitly specify the timestamps if needed.

AFAIK, people don't usually bother. As long as you can map from specific
time zone (applying the currently active summer clock time changes) to
something like seconds from epoch, you can always calculate back to you
preferred time zone. Look at https://www.emacswiki.org/emacs/Usergroups.
They say, for example, "Europe/Berlin", which may be either CET or CEST.

In any case, selection of time zone for user timestamps is not something
we need to worry about in Org code. Users are to decide. Org might
assist, but I do not see anything meaningful we can do to help with DST.
