Not sure who is your "they". In my experience, what I've seen users
want is "auto-indentation" and by that they mean that the text should be
kept indented when they hit RET and a few other keys.
E.g. a question I've seen many times is
So I tried this Emacs thingy which claims to do indentation for me,
but all my text stays at the left-margin. What am I doing wrong.
and the answer I generally see given is:
You want to bind RET to newline-and-indent.
Are these the majority, users? I don't know. But so far, you're the
only person who's complained about ?\n being in the default value of
electric-indent-chars, so I see no evidence that your preference in this
regard is representative.

Very easy: remove ?\n from electric-indent-chars.
IOW (setq-default electric-indent-chars nil) should do that for you.

Let's see if/when this leads to a concrete performance problem, and at
that point we'll see how to fix it. Making a marker point nowhere is an
annoyance and is itself a costly operation (O(N) for N markers), so
I don't much like using the workaround you suggest.
