We discovered some settings we needed to change on cloudflares side,
that aren't actually exposed through their API and this not exposed
through terraform. In order to make sure these settings aren't lost
when people look at how cloudflare is setup (and maybe use that to
duplicate in other environments), we will do a work around where
we capture this information in terraform, so people will see it
alongside other terraform configuration.
