Not all that much no.  Even the existing conversions
of formats missing newlines isn't all that important.

It's only a consideration for relatively unmaintained
old drivers and arches that still use printk without a
KERN_<LEVEL> where a message might either be interleaved
with a pr_<level> style message without a terminating
newline or by old style messages that should actually
instead be coalesced because the printks don't have
any KERN_<LEVEL>.

Much of the noise has already been filtered out by patches
and the ambient noise is already at a relatively low
level.

Quiet is good though and I think the noise reduction
is useful and quite painless.
