Is a zero register useful with modern OoO?

Can someone see a practical use for a zero register on a modern high-performance OoO CPU?

In the past it made some things easier, but it's not clear how it would offer much benefit now.

I'm talking integer, you could argue with FP that 0 and 1.0 are used often (are they?) encoding them in the ISA is better than doing a load.
