Good idea or bad idea for YAML metadata?

title: "My report"
author: "Tristan Mahr"
output: html_document
params:
knitr_chunks: !r
knitr::opts_chunk$set(comment = "#>",
collapse = TRUE,
fig.align = "center")
knitr_knit: !r
knitr::opts_knit$set(root.dir = "../")

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