It seems that the Linux keyboard layout is very old, and too few
keycodes were envisaged for existing key combinations. This led to
Meta_Tab being used sometimes for <alt><tab> and sometimes (wrongly in
my view) for <shift><tab>.
Thomas Dickey has tracked down a bug "fix" in SuSE GNU/Linux from (I
think it was) 2007 where someone recorded that the change was made to
assigning <shift><tab> to Meta_Tab, but without noting down any reasons.
TD also justified the change in ncurses-6.3 by saying that the
<shift><tab> key assignment had come to prevail in the main GNU/Linux
distributions, and this change merely reflects current practice.

Thomas Dickey is already in the conversation, having answered a post to
bug-ncurses@gnu.org with Subject: Emacs difficulties in linux console
with ncurses-6.3 caused by kcbt=\E^I. That thread was cross-posted to
emacs-devel.
The conversation has not yet been resolved.
