The problem is that many (most? all?) editors cannot easily
be configured to differentiate between them, i.e. insert
literal ASCII tabs characters when the <Tab> key is pressed
for indentation, and insert ASCII spaces when the <Tab> key
is pressed for alignment. *And* treat the alignment spaces
transparently like tabs, just like the indentation spaces.
That's probably not easy to implement, and it gets really
messy when you edit the line, remove or insert stuff between
the alignment spaces and the indetation tabs and so on.
Then suddenly alignment can become indentation, and vice
versa. The editor would then have to transparently convert
existing ASCII tab characters to spaces or vice versa.
This is a huge can of worms.
That's another good reason to let the old ASCII tab die and
rest in peace (or "lost in space" ... ok, bad pun).
Best regards

PS: Don't get me wrong, I'm *not* proposing to change the
style(9) sections dealing with tabs. Heaven forbid! ;-)
