And claiming that hydrogen doesnt need much development is an insane claim given the money put in and the total lack of success.
Not everything is a consumer car and truck. Being a battery maximalist prolongs the time everything else runs on dead dinosaurs.
Emergency vehicles of most types don't need that however. And in many of the cases you mention swappable battery packs are an option as well.
But we have to realize that compared to all consumer and fleet cars, 99% of all trucking is the vast majority of fuel use in transportation.
Extreme long range trucking is the exception.
In most cases you would make the hydrogen into methanol and you can keep mostly the same engines.
It makes indeed more sense to just use renewable gasoline, e.g. using the Fischer-Tropsch process like VW's eFuel.
Yep, BEV are great for commuting, but very difficult to use if you need to travel long distances in remote areas or tow a caravan or trailer.
Long distances are no problem unless you you are traversing unpopulated area free of infrastructure, and that is likely 0.000001% of all driving.
