We went over this several times on the Tech Log threads - the designers did not intend to inhibit the Stall Warning below 60kts IAS, the Stall Warning was silenced because the AoA data was not valid below that IAS. I'd be prepared to wager any amount you'd care to name that this is true for most, if not all, modern types. As was discussed on the Tech Log threads, latching Stall Warning on would work in this scenario, but would not work in a scenario where the <60kts IAS value was false.

It's obvious what BOAC meant.
Would you care to enlighten me? In all seriousness, I'm here to learn.
