Europeans have been nitpicking above info to me privately. I'll summarize 
what was said to me:

KPNQwest blocks were dealt with differently depending what country this 
was for. In some cases, the blocks were converted to PI by RIPE. In some 
cases other companies bought KPNQwest operations for particular country 
and became responsible LIR. Those LIRs did not mind about other ISPs 
announcing parts of those ip blocks separately although RIPE is as of 
late been trying to get them to clean up that space and things may change. 
Additionally there were some early blocks from KPN to begin with where it 
is not entirely clear if they were supposed to have been PI or PA and
those were resolved to PI. Also notable is that former KPN techs and ip 
admins after the company was gone, on their own time and without getting 
any compensation worked with RIPE to try to resolve the issues as much as 
possible and to help their former customers.

Additionally with permission I'm reposting the email on how the issue of 
customer with PA space changing ISPs is dealt with:

Hi!

As I'm only reading nanon on the web, one small data point:

In ripe-land, it is common to route PA-adress space for approx. 6
month after some customer switched ISPs.

So the customer has approx. 6 month to renumber, and that should
be plenty for everyone...

After those 6 month, all bets are off 8-}
