I'm actually not strongly biased on this for our main usage.  However if we do 
go the compatibility lib route I see it as a convenience that would allow us 
(where logical) reuse class names.  i.e. KLineEdit and KDE3::KLineEdit (Not 
that I expect much to change there, but just using that as an example.)

I assumed this was referring to the case above -- it makes it fairly easy to 
partition things off for use in backwards compatibility.

Well, that's subjective.  Once you're used to working with namespaces (which I 
do in some of my non-KDE code) using "K" as a namespace instead of using the 
language's facilities for such looks ugly...

Again, I'm not strongly biased, but much of the newer stuff in KDE is using 
namespaces.  I'd prefer that we standardize one way or the other though -- I 
don't particularly like having a minority of KDE using something other than 
our "standard" convention.
