Preserve query parameters on redirect

Support
66

Hi everyone, I’ve implemented the following in our netlify.toml file:

[[redirects]]
  from = "/"
  to = "/fr?utm_source=:source&utm_medium=:medium&utm_campaign=:campaign"
  force = true
  query = { utm_source = "source", utm_medium = "medium", utm_campaign = "campaign" }

From my tests, any combination of these 3 query parameters (including 2, 1 and no query parameters) in the URL lead to a correct URL. Am I missing something, or is this indeed enough to redirect for all these 3 parameters?
