Well, TeXLive team made this announcement several years ago:

\subsubsection{2004}

2004 saw many changes:

\begin{itemize}

[...]

\item \textsf{pdfetex} is now the default engine for all formats
except (plain) \textsf{tex} itself.  (Of course it generates \acro{DVI}
when run as \textsf{latex}, etc.)  This means, among other things, that
the microtypographic features of \textsf{pdftex} are available in
\LaTeX, \ConTeXt, etc., as well as the \eTeX\ features
(\OnCD{texmf-dist/doc/etex/base/}).

[...]

\end{itemize}

So this is the design decision of the distribution authors, and this
behavior IS expected at least by those who read documentation
[disclaimer: I myself do not read all the documentation, but since I
translated TL guide to Russian, I've read it].

One can quote various reasons for this decision, but I was convinced
by the following one: novice users may appreciate the fact that
microtypography and etex extensions work "out of the box".  If someone
needs "original Knuthian TeX", he or she is probably a more
sophisticated user, who can easily generate the required formats using
the tools provided by the distribution.

Note that pdfetex satisfies the trip test, so all documents that can
be typeset processed with the Knuthian tex CAN be processed by pdfetex
and give exactly the same result (the opposite is, of course, not
necessary true, as you point in your letter).

Good luck
