In a mining pool, all miners are working on the same exact block with the same exact coinbase.

Are you sure about this?
I heard that newer version of stratum allow each miner some kind of flexibiliity

there are only so many nonces, and (timstamp) extra-nonce
an average asic can run through these in seconds.
a pool needs to adjust coinbase data(extra-extra-nonce) to give more varied work over the ~many minutes of a block solve session. and do this for each asic.

a pool of say 13,000 asics will have 13,000 'new work' with different coinbase every few seconds, meaning over the average ~10min blocksolve session thats probably about 4million different 'work' with different coinbase extraextra-nonce

each asic gets a basic template of their owners blockheader including owners address

and each few seconds. the pool changes

in other pools, its the same thing, all thats different is the payout
