I can attest to this usage being common in New Jersey and New York City, in the US. So common indeed, as I see it, over the last year or two at least, that I just heard used in the last few minutes at a cafe, and found it to be in line with my expectations. I expect to hear it on a near-daily basis.
I am not sure that we can come to any conclusions about changes in the meanings of the verb "to do," though I wonder. This appears to be an idiomatic use, which may already fit into the way we thought the verb worked. But maybe not. Clearly, "do" has taken on a broader, non-specific meaning here. It struck me as strange when I started to hear it.
People seem to sometimes use To Do in various contexts to indicate a process that can be described generally, or broadly, which is already known, but not requiring specificity to be completed (or perhaps where such specificity is not comfortable). Though they don't always choose this. This is described more precisely and clearly in a couple answers provided earlier.
For example, in an argument about a relationship:
"I can't do this."
"Don't do this."
In the context of Nike:
"Just do it!"
Others:
"Are we really doing this, right now?"
"I don't do stadiums."
"I would do a light hike."
Answers provided earlier also provide some very appropriate examples
