Using that rule, there should be a TURKISH CAPITAL I which lowercase
as U+0131 LATIN SMALL LETTER DOTLESS I, and similarly, there should be
a TURKISH LOWER CASE I which uppercases as U+0130 LATIN CAPITAL LETTER
I WITH DOT.
However, I agree with you on the source separation rule, but I also
maintain that there was not much pressure to unify the alphabetic
scripts simply because of the small number of codepoints concerned:
all of Latin, Greek and Cyrillic including modifiers, combining
characters, numbers and unassigned codepoints still account for less
than 2000 codepoints; all the alphabetic scripts in the BMP combined
acount only for 8192 codepoints (not counting the Arabic presentation
forms and halfwidth/doublewidth compatibility variants, but counting
unallocated codepoints.)
