Did Honda think we were so nostalgic for retro classics that we missed fiddling with the inner bits, too? Sad.
As for me, I dutifully check and precision adjust my valves via shim replacement every 8,000mi and set them back to center of spec... all the while wishing I didn't need to.
Wooo, recognized that instrument cluster immediately. Good memories. I had the '84 in blue-black non-tariff 750cc beater.

I haven't looked into what the Nighthawk valve diameter (and lifter) sizes were- but all lifters have to be a certain size for a given cam size- and valve size - and revs. As well as oil viscosity. Lots more to it than first glance.
That being said - I am still surprised nobody has done a Nighthawk knock-off with one of our CB. It readily lends itself- especially with the STD tank shape.
Staintune muffler looks right, the headlight shroud I see many people have looks right...hardest part would be tail section I guess...

I think Mr P was going for the 750/900/1100F look.

I'm betting they didn't explore using hydraulic tappets on this motor in order to keep the cost as low as possible and give the dealer network a major service item for them to make $$ on.

I would agree.
Thinking conversely, Honda's recent track record on solid lifter management is pretty consistent with use not on just the CB1100, but with many and maybe most of their product line.
