DEB822 format is
- supported since Debian bookworm,
- used by
extrepo.
In my opinion, the resulting configuration files /etc/apt/sources.list.d look nicer in DEB822 format. Seems easier to modify.
However, in manual repository adding instructions, one-line style format seems easier for copy and paste.
