I tend to perhaps be a bit too concerned about performance, so I try to stay away from things like tagged types when I don't actually need them (which is most of the time). But for some reason, there are some features that seemingly require tagged types for no reason - custom indexing and iterators.

This line of thinking is terrible, and you're being insulting to somebody asking questions about the language. Way to go !

Ada forcing tagged types on you to use certain features *is* a problem, if only because certain Ada users are forbidden to use tagged types altogether and thus are prevented to use a lot of useful features.

With that said, I agree that if you can use tagged types, and your only concern is an hypothetical performance problem, then go ahead and use tagged types. As explained in another mail you can even choose by call-site if you're going to dispatch or not.
