Sterile substrate
Where nothing grows
The obvious version of this idea provides liquidity to the biggest graduated Pons coins and lives off their trading fees. That cannot work, and it is not a judgement call — Pons pools pay liquidity providers nothing at all.
Pons attaches a hook to every graduated pool. Its address encodes its permissions in the low 14 bits, and 0xe044 & 0x3FFF = 0x2044 sets AFTER_SWAP_RETURNS_DELTA — the hook takes the entire swap fee for itself after graduation. The pool's own fee tier is set to zero, so nothing is left to accrue to anyone providing liquidity.

feeGrowthGlobal only ever counts upward, for the life of a pool. Reading zero means no liquidity provider has earned a single wei in any Pons pool since the day it opened. Every graduate also carries the same 2.9277×1022 of active liquidity — Pons's own position, and nobody has ever joined it. There was never a reason to.
