Yes, but exclusion suggests that there might be use of software later that doesn't allow it, or that there's some difference -- like they do some DB thing and it doesn't work if you're using ext/zfs/whatever. Remember it's for non-experts, people may not even know(?) that pgsql and such are freely available to them.
At least having the add-apt-repository line in the course manual saves you looking for it on the DBeaver page.
Aside: I've been doing a the Standford machine learning course and it includes installing in the required work, so I did the install on Windows as instructed (what a pallaver) and only then realised it was entirely optional just not presented as such and so then did `sudo apt install octave`, messed around with a few test queries, and was done with the entire second lesson.
