The two reasons in favor of a language feature are:

1. It might be more readable.
2. It allows ranges to include the *.max value.

The first is obviously just a cosmetic issue, which I don't think is 
worth it on its own. The second makes it easier to work with an edge 
case, which I don't think is worth it on its own either. Solving both 
together is a little more worth it, but enought to warant a language 
feature, I have some doubths.
