In broad strokes, we don't disagree, you know
I was in contact with a Boeing test pilot. He said the 777 does slow more quickly *while solely relying on the autothrottles* during a crosswind landing. That's true to every airplane cross-controlling or putting in a large rudder input. He said due to the autothrottle retard software it's more noticeable on the 777 and can lead to harder landings. Most guys just set the landing attitude before going to idle. The slight speed decay isn't an issue for guys using manual thrust. Or if the pilots are autothrottle dependant they just override the retard throtlle a bit during the last portion of the flight. It's similar to every cross-control landing but a bit more noticeable on the 777.
He mentioned that the increased probability of a hard landing is true but the reasoning ('loss of lift', 'lack of stability', long wheel base, etc) aren't the cause. "It is a teddy bear
Other planes have similar issues, like 727-200's, 737-800's using Flaps 40, etc. It's more common for guys to not go to idle starting the flare. Instead they set the landing attitude/cross control and once that is established and touchdown is about to occur then power is reduced to idle. Let's say it's 'power to idle at 10'' becomes 'hold your power until just prior to touchdown.' It's a small delay in thrust reduction.

Heathrow is my base. On the 27L it is very common to experience a microburst. Having said that, the T7 is shaky during decrab at the best of conditions. And if we're being honest, there's a lot of incidents lately where excessive vertical stabilizer action has been performed.

Lightning map matches up with the wetter regions with severe convective activity. Panama and Cuba, as well as Puerto Rico's infamous 'Mayaguez monster', are completely different than LHR's rain. Those areas are dark red...LHR is in the pale gray (little activity) region.
