Just my opinion, but I don't see that the 255 bar item is in any way related to the Making Medleys topic being discussed.

The maximum number of 255 bars is in place for any and every song, however created. The discussion here is centered on Making Medleys.

If you need more than 255 bars for your medleys, just use multiple choruses, like the designers intended.

However, if you need more than 255 bars for any one chorus, then you could add the request (again) to the wishlist
