>From a licence point of view reimporting the database is the important
step (if you are actually publishing/distributing the data or products),
that gives you the freedom to licence tiles as you wish as long as you
attribute.

I personally believe that this is really a non-issue, we will literally
have 100s if not 1000s of sites with slightly "wrong" attribution
strings for a long time.
