Devs claim that it improved performance in their particular benchmarks. I guess the best is to try it for yourself.

(+) presumably those that tested and got a performance gain never bothered to write a ticket or a word of praise. so keep that fact in mind.

But do carry out tests if you are hitting the performance ceiling. A particular use of a particular construct may be hampered when people rewrite a piece of code. So while the overall performance might improve, your case may not.
