Sure.
I'd argue the kind of things I mentioned --excluding artifacts like the Machine of Lum the Mad and the Apparatus of Kwalish-- weren't peripheral at all. They were the kinds of things that helped define D&D-style fantasy. I should note the majority of campaigns I've seen featured portable holes and run-ins with D&D's classic, protected-IP monsters --were your actual play experiences significantly different?.
Yes, mine was significantly different.
Beholders? Only faced them in a computer game.
Displacer Beasts? only in one of the Gold Box SSI computer games
Blink Dogs? If I encountered them, it was in the same computer game as the Displacer Beast
Drow? only in the D-series of modules and Q1 and that was the only time back in 1e.
Carrion Crawler? Not since switching from Holmes to 1e
Gauth? Never
Githzerai? Never
Githyanki? Never
Kuo Toa? Only in the D series back in 1e
Mimic? a couple of times early in 1e
Mindflayers? Never
Morkoth? Nope
Otyugh? only in a computer game
Owlbears? Never
Roper? Never
Rust Monsters? Never
Shrieker? back in Holmes or early 1e.
Slaad? never
Umber Hulk? once in a module
Yuan Ti? never
Cloaker, Ear Seeker, Lurker Above, Piercers, Rot Grub? Nope
Of the above, the only things that interest me are the Yuan Ti and, maybe, the Beholder, Carrion Crawler if they are used very sparingly.
As for spaceships, only once when we went through S3 back in 1e and I thought it was lame back then.
