Tim Beiko observed that EOF proposals had been repeatedly proposed, delayed, and modified over several upgrade cycles

Quotes that support claims

Different variants of EOF have been proposed, included, and subsequently removed from network upgrades over the years (see Shanghai, Dencun), often reflecting shifting consensus about its urgency relative to other core features. Last year, EOF was scheduled for the Pectra upgrade until the fork was split to minimize scope, moving both PeerDAS and EOF into Fusaka.
