What is the reason for different workchains to use account identifiers that are shorter or longer than the "standard" 256 bits used in the masterchain?

What is the reason for different workchains to use account identifiers that may be shorter or longer than the standard 256 bits used in the masterchain?


2.1.1. Account addresses. The source address and destination address are
always present in any message. Normally, they are (full) account addresses.
A full account address consists of a workchain_id (a signed 32-bit big-endian
integer defining a workchain), followed by a (usually) 256-bit internal address
or account identifier account_id (which may also be interpreted as an un-
signed big-endian integer) defining the account within the chosen workchain.
