At many of our customer sites the log level is set to KERN_DEBUG. It

That argues for adding some KERN_INFO "still booting" messages
not logging unnecessary KERN_DEBUG messages.
Actually I would think that argues for reducing boot times on these
large systems.
Right.
That's an independent argument, but sure, go ahead
and do that too.
Here is output for my workstation a simple 4x box
-bash-4.1$ dmesg | grep "type [0-9][0-9] class" | wc
12 108 804
-bash-4.1$ dmesg | wc

Here is some output from one of the biggest boxes.
-bash-4.1$ dmesg | wc

-bash-4.1$ dmesg | grep "type [0-9][0-9] class" | wc
