Requirement for dishwashers in dwellings to be GFCI protected wasn't even about shock/electrocution when first required in code (IIRC it was 2014 NEC that first introduced this) What triggered it was a component failure (not even sure what component) that tended to start fires but they found that a ground fault also developed when this failure occurred and GFCI would trip before it started a fire. IMO that should have been a product recall thing and not a freebie for the appliance manufacturers by letting the GFCI bail them out on this defect.
The HVAC units was triggered by one electrocution incident that had a bad or missing EGC and unit frame was energized. That can happen with anything if not installed properly or something is damaged, yet the number of these types of incidents isn't really all that high.
Laundry equipment - IDK, kind of suspect sort of a "because we can" requirement. I may be somewhat ok with requiring it for 5-15 or 5-20 receptacles as these have long been a problem with missing EGC pins on cord caps and a main reason many other locations over the years got added to the list of receptacles requiring GFCI protection but was almost entirely 15 and 20 amp 125 volt receptacles that required it. Then they started adding more receptacles - anything 125 volts to ground and up to 50 amps - no real good reason AFAIK those rarely are missing EGC pins unless someone intentionally removes it, they don't break off unintentionally like some 5-15 cord caps seem to do easily.
Then when they started adding three phase receptacles as well I remember reading the PI/comments on that and it basically said something to the effect of "we now have that capability", nothing about any sort of shock/electrocution incidents or related statistics that show there is any significant trouble with these applications. I fail to see any significant number of compromised EGC pins on cord caps in these applications as well and feel this had to be pushed by the manufacturers more than any other group. They may not sit on the CMP that handles this section, but you can bet they are going to present information to try to convince those on that CMP to help sway their decisions on making these code changes.
