Sorry, that's not correct. Ever since the yum days, they have been
different. The key differences are these two bits (from `man dnf'):
[...]
dnf clean packages
Removes any cached packages from the system.
dnf clean plugins
Tells all enabled plugins to eliminate their cached
data.
dnf clean all
Does all of the above.
By removing packages, you are losing the ability to do offline
transactions. Cleaning cached data from plugins, can do any number of
things depending on the enabled plugins. So please stop repeating this
obviously incorrect information.

During the yum days, the most frequent complaint on this list were: why
is yum so slow, I hate waiting for metadata updates, .... and so on.
And now people complain, the cached metadata is out of date (please
don't confuse this with actual bugs). There is no winning, you either
wait for the metadata to download, or you get a responsive interface.
PS: I've no relation to the dnf team, just a user. I however think
instead of complaining on the list, if any discussions here lead you
to think there is a problem with dnf (as in a bug), you should file
bug reports.
