OK, thanks for clarifying - apologies for any misunderstanding.

It's not a good thing because it takes up people's time that could be  
spent better elsewhere.  It's difficult to support old platforms when  
newer APIs can be used.  There are going to be more conditionals in  
the code, which makes it less readable.  People will be less likely to  
submit patches for these reasons.

Again: would it be possible to mix and merge parts of the ports, e.g.  
use YM's event handling code, which is possibly (!) superior?  I have  
seen a number of unexplained crashes with the Nextstep port which  
usually occur somewhere in the event handling code.  I don't know if  
this is the possible bug that Yamamoto-san pointed out a few times.
I would also like to try out the grand central dispatch method within  
the NextStep port.
