The "common sense" here seems like yet another "personal preference".

There is no stuff of mixed left/right alignment and [supposed to be
treated as of mixed] paragraph direction in a newspaper. E.g.,
paragraphs in a Hebrew newspaper are entirely RTL, as defined by a
"higher level protocol" -- preferred paragraph direction associated
with the language they are written in.

No, it does.  When the paragraph embedding level is constant
(and as a rule you are aware what this level is), the thing
loses any ambiguity. On the contrary, with the automatic dir,
ambiguity of *mixed* Bidi text persists.

I read it in the same way as I use to read a newspaper -- applying a
"higher level protocol".
Anyway, even the same level of ambiguity doesn't give any pros
or cons to either approach.

The both are permissible, and to suit different "personal
preferences" there must be some way to switch between them.
