This is not about "perfectly compatible rendering", it is about
legible rendering. As specified in the Unicode standard. Another
example below.

You seem to be confounding directionality with alignment. While, for
plaintext, I would find it preferable if the two always matched, this
is not what I'm asking for, and not what I see as a requirement for
making plain text usable.
To be clear: If I write a file containing a single line (this is all
English, no special use of capitals), the iconic:
Hello, World!
then, when I open this file in a standard-compliant editor, I'm ok with
seeing (centered)
Hello, World!
or (right aligned)
Hello, World!
or even (wrapped at a surprisingly short line length)
Hello,
World!
Indeed, these are presentation issues, where fidelity is not expected,
almost on a level with font and color.
What I'm not OK with is:
!Hello, World
Which is what you'll see if your editor decides to use RTL
directionality for this file, as the FAQ says it may. What I'm asking
is that we stop calling this behavior "standard compliant"; and I refer
you back to my first message in this thread[1] for an example of the
mess that this creates with true BiDi text.
Thanks,
Shai.
