After all this audit work, is Hyvä migration still worth it?

Yes, almost always. Even with 5-10 Partials and 1-2 Blockers, the Hyvä migration cost is recovered within 3-9 months of going live for most stores: 8-25% conversion lift from speed alone, lower hosting bills (fewer JS dependencies), and faster future feature builds (Tailwind+Alpine is roughly 2× productivity for frontend work vs Knockout). The audit just makes sure you go in with eyes open and a fixed budget, not with surprise rework eating the savings. Every store I’ve migrated since 2024 broke even on the Hyvä investment within a year.
