Iranians have used conventional optical tech. The promise of the F35 is to be detected late by conventional long range radar. They were never supposed to be invisible or quiet.

Granted that makes the stealth advantage very limited in terms of usage: coming from far away undetected. Then be very visible.

Besides yes, China claims they can detect them with their satellites network and a France military equipment maker is apparently developing a radar that detects stealth jets. So that advantage is apparently not going to last.

Given that modern air combat is all about beyond visual horizon attacks, I'm not sure how being hard to detect by non-visual means is limited in terms of usage.

Let's step back a bit: stealth is about reducing the apparent size for radars. Being stealthy doesn't mean you're undetectable, but you will see a (non-stealth) enemy jet before it sees you. Then you fire a missile… and are instantly detected!
Air combat superiority will do only if you're still beyond missile range at that point. Otherwise the other side also shoots back a long range missile at you, and it's likely to end in mutual destruction. And even if it's not, you revealed yourself, so better not be outnumbered. That reduces the usage in air combat.

For air to ground, which is what happened here, same idea, except there are a lot of things you want to drop on a target that requires a certain proximity. The benefit of the F35 is it can theoretically take out air defence systems before being detected (again: providing the enemy radar does not have one of these next-gen fancy radars that can detect it). That's what happened in Iran… except that the whole scenario assumes once again conventional air defence: SAM batteries are typically massive and well "visible". They were destroyed before any jet would get close. But Iranians have APPARENTLY (I don't think that was clarified) used a much smaller launcher that conventional SAM, maybe even on man's shoulder, that was not destroyed, and worse: since it was optical/IR based, it didn't emit any radar signal and the F35 didn't see it coming (it didn't launch flares nor done any evasive move).

So, once again, the F35 niche app was to take out SAMs and that was revealed insufficient.

Now, was it an excess of confidence and could the F35 have performed its mission without exposing itself so much? We don't know. But the point is this is a flagrant demonstration of the limit of the "stealth" claims that often sound like a magic invisibility coat. I maintain: stealth does not have that many use cases!
