Drop tests were also performed.
How serious is that music though makes it seem like something important was being shown off.
Well, there are plans to acquire the F-35A for training, so some of the fleet should be able to do so. And JSM for the F-35B, is proceeding, just not internally due to the smaller bay.

Well, Many US SEAD aircraft can generate co-ordinates / bearing from a sufficiently sustained / pulsed contact and Semi-automatically Shoot back in a “Self-Protection” mode.
As far as the ones I have documentation for, this includes the; Wild Weasel F-4 variants, A-7E, F-16CJ (ASQ-213 “Rev. 7” and later) & AH-64D / RAH-66, I’d have to look more closely at others.
So It’s likely that the F-35’s retain said capability, so anything with GPS guidance could cover said shortfall to some degree, but the AGM-88 and SiAW are planned for integration on the various F-35s. And any inventory built for the Typhoon as a stop gap should help, Though I’d wonder where a revised and modernized ALARM would sit even if it’s not being pursued.
You really aren’t the only one referencing this, and there doesn’t seem to be any great option for the F-35B specifically. Theoretically if the P-JDAM were to ever be picked up again it could serve as the basis for an option but that seems unlikely.
But is mostly a remnant of being forced to use a design for what should have been four or more different aircraft. Thus needed to make concessions to achieve various goals, the fact that so many stores can’t actually fit the bays of the F-35B is likely an oversight, and to some degree an artifact of needing to intuitionally retain the Harrier’s VTOL capabilities.
The F-35C or a redesigned stealthy Harrier / Clean sheet would have been the better option. And its not as if the USMC wouldn’t have bought it (and do joint production “right” this time). and the F-35A & -C would be all the better for it.
Sure, but what was promised? All it seems to be is a baseline Stealthy Airframe at the F-16’s price point, intended to serve as the “Low” end of a High-Low mix for the F-22 / F-47.
