The definition of "Senior" has now changed to "has > 5 years of experience". Combine this with the tendency of people to move every two years (because companies rarely keep up with the market), and you can see that "Senior" casts a wide net. It essentially includes people who may have seen maybe one major iteration of a product, perhaps none. In my opinion, that basically translates to a junior.

Well, that is a highly subjective opinion.

As with everything, moving every 2 years has pros and cons. The flip side of what you said is that a person who spent >5 years at the same company has only really seen a limited number of problems, methodologies, technology stack. And that could also count as "junior", right?

The five years is the issue, imho. As I sometime put it: this role needs someone who’s made a lot of mistakes on someone else’s dime.
