Hi.
I'm actually amazed how many people comment without having a clue what they are talking about.
What you're describing is not an issue but the fix of an issue ๐
When the kernel boots with the parameter quiet, systemd should get the option systemd.show_status=auto
. With this option it should only inform about failures and such like. In current releases this finally works.
To get the old behaviour you just have to add systemd.show_status=true
to your kernel parameters.
Yes that's the recommended path.
Information on how to upgrade can be found in the official documentation:

As others pointed out it might be a PITA. Depending on your installed software and configuration a new install might be easier.
