FWIW, I almost gave up from going from 24.3 to 27.1 precisely because of

  electric-indent-mode 

without knowing that was the cause of the new behavior (in my
perspective).  Today I was writing some TeX and the following happened.
Let me use ``[]'' to represent the point.

--8<---------------cut here---------------start------------->8---
\noindent {\em Notation.} As we often write polynomials in
finite rings of characterisc 2, let's define
%v
  \[\poly(x) = ...\]
%e
in the same way that it was used in the introduction.  []%% Well...
--8<---------------cut here---------------end--------------->8---

When I pressed RET, I got this

--8<---------------cut here---------------start------------->8---
\noindent {\em Notation.} As we often write polynomials in
finite rings of characterisc 2, let's define
%v
  \[\poly(x) = ...\]

I have been reading this thread, so I just turned it off for the first
time.  I got used to it in other ways, but this behavior up there made
me turn it off and leave it off from now on.  (And it scared the hell
out of me when I saw it first.  Lol.)

Having said that, I recognize that many times I get to see new features
because they become the default.  It takes a long while for me to
actually dig new features as an attempt to solve a problem.  But you
know me by now --- I like stability a lot and so I stick to a version
for many, many years.
