Second thought: why do we have to insist on 64 payload bits?

Because 8-bit bytes won (over 6-bit bytes and 9-bit bytes.)
Then 8×2^k became the size of each larger data type.

64-bit format with 2 or 3 flag bits and 62 or 61 payload bits appears
to simplify system issues at relatively small cost in storage density.

Loosing an easy ability to go for 128-bits or 256-bit arithmetic.
