The conversion is clearly not loss-less. :)  So it's like asking what
would be the pros of backing an SVN checkout with an SVN repository
instead of a Git one (or a CVS one for that matter).

I'm sure someone who cares more deeply about version control than I do
could give you a list. :)

But that's not really an argument I'm interested in pushing.  I
believe eventually the remaining SVN users will switch to distributed
version control of their own will, and we'll eventually decide to stop
supporting SVN because not enough of the project is using it to
justify causing the majority of users to use a translated solution.

But we have larger problems to solve in WebKit besides what version
control system we're using. :)

I'm sorry for re-starting this thread and distracting from more
important discussions.  It just crossed my mind for whatever reason
again this evening.
