I suspect the answer is “as far you’re concerned, no, it’s not going away.”
I say it that way because I’m interpreting your question as “can I write this expression and have it evaluate to the same thing”, but the deprecation message you’re getting is likely related to deprecation of .< as a generic function that will be replaced with dot-broadcast syntax. But that’s a change in how that expression gets evaluated, not in what it evaluates to.
