The Yi Syllables area isn't listed in Index-3.0.0.txt, whereas, for
example, the CJK Ideographs Area is listed:

bash.exe-2.02$ egrep -i area * | egrep -i -e cjk -e yi
Index-3.0.0.txt:CJK Ideographs Area 3400
Index-3.0.0.txt:CJK Phonetics and Symbols Area 2E00
Index-3.0.0.txt:Ideographs Area, CJK 3400
Index-3.0.0.txt:Phonetics and Symbols Area, CJK 2E00
Index-3.0.0.txt:Symbols Area, CJK Phonetics and 2E00
UnicodeData-3.0.0.html: <li>Added place holders for ranges such as CJK Ideographic Area and the Private Use Area. </li>

It would be useful if the ends of the allocation areas were also
listed somewhere, since the areas are not contiguous.

Organising the character block descriptions in the Unicode Standard,
Version 2.0, by their allocation area was an interesting way to
deemphasize the concept of "area". I note that the character block
descriptions in the Unicode Standard, Version 3.0, will not be
organised this way.

Thank you for the rest of your explanation (which I omitted from this
reply for sake of brevity).
