Emacs is over 40 years old, and has seen many fads come and go.  It has
been steadily acquiring new users in that time, and losing old ones.  As
a program it combines extreme user friendliness with a long steep
learning curve (i.e. it is not "beginner friendly").  I don't think we
should be trying to change these attributes.

Many of them, faced with a choice between lots of clones which behave in
a beginner-friendly, but suboptimal fashion, and the freshness of Emacs
will come to chose Emacs.  We should not deprive them of this choice by
dumbing down Emacs.

Incidentally, the current discussion, in essence, has been going on on
this list for the last 20 years or so, and probably quite a bit longer.

I suggested something similar some years ago, but never got around to
implementing it: that there be several sets of defaults, and a user
choses a set of defaults by the name of the command she starts Emacs
with: for example, I would start emacs-classic, whereas you would start
something like emacs-cua.  This could be implemented by hard links, with
the Emacs binary finding its "pre-"initialisation file by checking the
name it was invoked by.  Or something like that.

You have to be careful that this doesn't mean dumbing down.

As a counterexample to your argument, look at the inconsistent series of
messes that recent versions of Firefox have become.
