There is anecdotal evidence that people intuitively use characters
from their native language, and then are surprised by the syntax errors.
Unfortunately, they are not required to report their usage to the
Ministry for Use Of Funny Characters In Programming Languages.

Are you also assuming that I make up my mentioning of anecdotal

I don't speak Farsi, Arabic, or Hebrew, so I can't comment on that.
I know that in German, if/while is not an issue at all. People
regularly read "if" aloud as "wenn" or "falls".

The emphasis follows the convention of RFC 2119; it's not an emphasis,
but an indication of specification.
3. SHOULD This word, or the adjective "RECOMMENDED", mean that there
may exist valid reasons in particular circumstances to ignore a
particular item, but the full implications must be understood and
carefully weighed before choosing a different course.
There are already deviations from that rule in the standard library:
all are not proper English words.
