In practice, search engines tend to ignore language tagging in favor
of statistical analysis of text, since language tags are so often
missing or incorrect.

There are various contexts where multiple language tags can be specified,
indicating that you will accept content in any of these, usually with a
priority order.

Not at all.

The same feature (the language-tag search list) can be used in that case
as well.

That's known to be a problem, yes.

We didn't pick the dates, the ISO 639-2 Registration Authority
(the Library of Congress) did.  You can go to
http://www.loc.gov/standards/iso639-2/php/iso639-2chform.php
and request a change.

As of ISO 639-2 and RFC 4646, yes.  In 639-3 and 4646bis, about
30 different Arabic language tags will be available:

aao  	Algerian Saharan Arabic
abh 	Tajiki Arabic
abv 	Baharna Arabic
acm 	Mesopotamian Arabic
acq 	Ta'izzi-Adeni Arabic
acw 	Hijazi Arabic
acx 	Omani Arabic
acy 	Cypriot Arabic
adf 	Dhofari Arabic
aeb 	Tunisian Arabic
aec 	Saidi Arabic
afb 	Gulf Arabic
ajp 	South Levantine Arabic
apc 	North Levantine Arabic
apd 	Sudanese Arabic
arb 	Standard Arabic
arq 	Algerian Arabic
ars 	Najdi Arabic
ary 	Moroccan Arabic
arz 	Egyptian Arabic
auz 	Uzbeki Arabic
avl 	Eastern Egyptian Bedawi Arabic
ayh 	Hadrami Arabic
ayl 	Libyan Arabic
ayn 	Sanaani Arabic
ayp 	North Mesopotamian Arabic
bbz 	Babalia Creole Arabic
pga 	Sudanese Creole Arabic
shu 	Chadian Arabic
ssh 	Shihhi Arabic

Those forms are too short, and there are problems with generic tags, as
centuries are not the appropriate units for many languages.
