What changes are you suggesting?
I found a really nice trick for redirecting (effectively disabling) ALL *.pages.dev domains under an account with one single Bulk Redirect. This is especially important for Free accounts, which only have 20 Bulk Redirects in total.
This nicely addresses a pretty widespread pain point in the community, so it would be nice to document this as a way to save up a lot of Bulk Redirects and manual effort in setting them up.
Additional information
This trick of course makes the "This will automatically redirect all of the preview URLs to your [target location]." part non-optional, but this is probably fine for most users.
