First come cirst serve, in that characters are encoded in the order
they a submitted to the IRG. Therefore a block or extension includes a
mixture of modern and non-modern characters. The order characters are
processed in by the IRG is based on when they are submitted not based
upon whether the usage of the character is ancient or modern.
Extensions C and D are the characters submitted to IRG on or before
2002, characters submitted from 2002 to the present will be this
system be put in Extension E, unless there is a change of IRG policy,
and any charcters submitted to the IRG in the future, if the same
approach is followed will be Extensions F, G, ...
Now of course some of the first set suggested are in wide used, but
not all of them, even in extension A there exist characters like
U+416B, that one could safely bet one million pounds against anyone
being able to say it's meaning or pronunciation.
To the best of my knowledge at no point in time did people discuss
what cjkv characters are in modern use and leaving space in the BMP
for them, or by the time anyone thought about this the BMP had already
been filled up with too much CJKV clutter.
