Good idea or bad idea for YAML metadata?

title: "My report"

  knitr_chunks: !r 
    knitr::opts_chunk$set(comment = "#>", 
                          collapse = TRUE, 
                          fig.align = "center")
  knitr_knit: !r

Curious why you can't just set those knitr options in the first chunk at the top of the document?

Of course I can. No reason not to either. Eventually, somehow, I'd like to use the same knitr options in several related documents, and factoring out the options into a single definition, using a yaml block, seems like the best route to that.
