How exactly are Illustrator’s Symbols more useful than Photoshop’s Smart Objects in your opinion?
Ah, I guess you meant the »Image Hose« functionality.
Does anyone know if there some reason that Adobe has not implemented symbols into Photoshop yet?
I assume (and I know that’s not the same as »knowing«) the cost and the benefit have not been deemed to be proportionate yet.
23 votes in six years would seem to indicate a modest demand.
No, I mean a symbol, like in Illustrator, Sketch, Affinity Designer. Image hose is completely different.
You update one instance of a symbol and all instances update, but on top of that you can edit text to be different and if you stretch an object it won't distort (rounded corners, etc).

Not familiar with that, how do you create instances of one Symbol with different texts in Illustrator exactly?
Edit: If it should involve using »Break Link to Symbol« it would not be an advantage over Smart Objects in my opinion, what with the way one can use the Layer Comps of a SO in the containing document.

How is that different from SOs updating?
Or are you talking about being able to edit an SO’s content within the containing document? If so the expectation to be able to do that in a meaningful way in Photoshop is unrealistic for the time being (considering the possible combinations of Color Spaces, bit depths, resolutions, transformations, Filter applications, …) and I think Mr.Cox has explained the reasons repeatedly.

So you mean 9 point scaling?
