I am not sure, because I do not fully understand how the new
implementation of `current-column' works in the wild.

My general understanding of the indentation is that it works "visually",
so that indentation makes things look aligned to graphical column in
the displayed Emacs windows.

However, I do not fully understand what happens if we try to indent
fully hidden text (like inside Org's folds). See my previous bug
reports: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=56837 and
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=58791

You mentioned in the past that indenting invisible text does not make
sense, although it does in Org, and things did not break spectacularly
after bug#58791 was fixed.

The overall design of `indent-to' is unfortunately elusive for me.
