That's a matter of taste at the moment, and so far nobody proposed to
hardwire a rule about it in 4646bis.  The posters on the review list,
members or otherwise, might develop some common preference.

The policies are stated in 4646, they could be adjusted in 4646bis
if necessary.  It's as you say, length 5 to 8, digits and alpha, or
length 4 if it starts with a digit, avoiding any confusion with
script subtags.

No.  There's no syntactical concept of a date in variant subtags,
and no prose about dates in variant subtags.  It's only handy for
cases like 1694acad, baku1926, 1926baku, or 1606nict.

IMO it doesn't.  Maybe your registrations start a tradition of
preferring years at the front, or maybe not.
