The safety net we are talking about is present only at the right bound of a

down code, but only a bit. And in many of such situations you probably
need to add a min(x, $) manually in the code anyway, so the overhead is
limited.
Personally, I have _never_ needed to add a min call like that. So, while _you_
may think that it's a common thing to do (and it may be that it is in your
code), that doesn't mean that that's generally true.

I agree. I've never needed to add a bounds check like that.
