A variant of this patch has been in Fedora since at least 2010 and AFAWCT there haven't been any complaints about the change in behavior.
https://src.fedoraproject.org/cgit/rpms/kernel.git/tree/silence-fbcon-logo.patch P. ---8<--- On text-based systems the 'quiet' boot option will show printk levels higher than CONSOLE_LOGLEVEL_QUIET. The displaying of the Tux logo during boot can cause some consoles to lose display data and as a result confuse the end user. Do not display the Tux logo on systems that are in 'quiet' boot.
