Do the studs on old style wheels have uses?

Talking about thiss wheel family:


These wheel rims were quite popular in mid to late 20th century, and the newest variant displayed above endured until 2006, as it featured a modern Technic pin connection, making it easy to integrate with modern builds. But still, can't help but wonder, what uses would these studs have? Everything I can personally think of is putting something like this on the wheels:

and then connecting them with a Technic brick or beam to produce a "wheels hidden inside the body" effect - possibly quite interesting. But nothing more. These wheels have now been retired for close to 20 years so maybe TLG didn't see much sense in continuing to make them either. But what do you guys think, do you have any practical uses for these studs? Mind showing me some models or MOCs that utilize them?

Windmills, and any build where you want something to spin or swing.

@Xfing I've turned them sideways and used them for part of steam / sand domes on steam locomotive boilers, like those seen up until the early 1900s.

Example: My MOC of the 2-4-4  'Fred Gurley' (Disneyland RR No. 3) I built for my father has these style of domes on it.

2x2 round flat tile, 2x2 round tile with pin and go from there with, e.g., a 1x1 round tile as wheel cap/cover.
