That is the expected current behaviour, "debug" can cause "too many" messages
to be useful anymore if things are broken.

Then use the kernels loglevel= parameter for the kernel only, not affecting
Base OS tools.

The generic term "debug" is read by Base OS tools too.

Like for the kernel, there are options to fin-grain control systemd's logging
behaviour; just do not use the generic term "debug" which is a convenience
shortcut for the kernel AND the Base OS.</pre>
