It's called "Design For Serviceability" and is usually just part of the long list of items that are "critical to design quality" that a design engineer is
supposed to work towards. But that's somewhere else, in a place usually known as Utopia. In the real world that we all live in, DFS cost $ just like any other design "features", which means that quite often in the rush to get a particular design to market on time and on budget, while retaining as many sexy features as possible, DFS often goes in the CFC.
It could be worse. You could be conscientiously trying to replace the air filter on a Triumph Trophy. <_<
To do that regularly scheduled maintenance item requires:
Remove seat
Remove rear luggage rack
Remove entire rear cowling
Remove fuel tank
Remove carburetors
Pull out air filter-box assembly
Replace the entire air filter-box assembly (you can't just get the filter inside, it comes only as an air-box assembly)
...and of course, "Reassembly procedure is the reverse of disassembly" Grab your spanners!
