Yeah. Keyboard trays also tend to feel cramped once you add a mouse. I wonder whether the desk height issue has to do with changes in work? It may be that when desk work mostly involved reading and writing papers (I sort of picture someone leaning over their desk to be closer to the paper), a higher surface was more ergonomic. And then nobody thought to change the default because the transition to computer dominated work was so gradual and unrelated to office furniture replacement cycles?
