It wasn't. systemd fixed its actual bug, which was a real bug that caused it to generate an excessive amount of debug output. With that fixed, there was no further issue and no need for a workaround. (The bug wasn't that systemd generates debug output when the kernel command line contains 'debug"; the bug was something else, which caused systemd to generate an absurd amount of debug output.)
