Yes, but if there is no constraint on the length of the variable field,
this is not a problem.

You actually don't even need an addressing scheme that is open-ended at
both ends. Just allowing for unlimited high-order bits will do. That
way, if you run out of allocations in 128 bits, you just add more bits
at the high end. Like patent numbers.

A fixed record that links to a variable-length record is effectively a
variable-length record.
