I disagree with the title and description of the bug report.

Journald, calculates a hard limit on logs (based on the system configuration).

$ journalctl -b -u systemd-journald.service -n 1
-- Logs begin at Mon 2018-09-17 14:21:50 BST, end at Thu 2019-03-21 15:16:25 GMT. --
Mar 21 11:27:37 ottawa systemd-journald[571]: System journal (/var/log/journal/1b8df0fa27039f0163586c6756a6d401) is 3.7G, max 4.0G, 231.6M free.

there is
$ journalctl --disk-usage
Archived and active journals take up 3.7G in the file system.

command, but that currently does not print the max size, and free, like journald does on startup. Maybe it should.

and --disk-usage is a bit odd, as it conflates the runtime and persistent journal numbers.

I guess --disk-usage should print more info, about runtime vs persistent logs; and the max sizes.

Now, do any of you have the max limits breached? Can you please paste the outputs of:
journalctl -b -u systemd-journald.service -n 1
journalctl --disk-usage
