Also for years Debian supplies short update 'diffs' - so user doesn't have to download multiple MB sized files - just couple short small files - again something much nicer then running a daemon to download tens of MB on background daily...
dnf/yum don't download metadata if it is not changed, the download a small repod.xml file with checksum and other stuff, metadata is only updated when the metadata in cache don't
match the ones in the remoted repositories.
Updates are only push once a day, and have to sync out to the mirrors, so there is no reason to check for metadata every 10 min og every time dnf is run.
both yum/dnf has settings to control how often the remote repos is checked for changes, so it can be configured by the user is they don't like tge default setting.
delta metadata is on the wishlist for dnf, but it is hard to get it to work in good way.
