Updated answer (sdkmanager >= 26.0.1)
As per the comment from @albodelu, this can now be done via:
sdkmanager --list --verbose
Which on my machine gives the following:

done
If that is too verbose, then you could do something like the following:
sdkmanager --list --verbose | grep -vP "^Info:|^s|^$|^done$"
Which uses perl-compatible regular expressions (-P) and a grep inverse matches (-v) to remove all lines starting with Info:, starting with whitespace (^s), empty lines (^$), and lines which only include the word done:

Old answer
In the mean time, another user figured out an ugly hack to get a list of full package names:
I used --list --verbose and it listed that it was searching some xml files in ~/.android/
So... this (ugly) *nix command prints out the (full?) list of the paths... (for anyone else who stumbles upon this thread before they get a sensible fix to this issue...)
grep -Riwo -e "path.*>" ~/.android | awk -F'path="' -F'"' {'print $2'} | sort | uniq
For reference, that gives the following output for me (including a bit of junk, but I don't care because at least I can see package names now:
