AFAIK, ISPs have long been encouraged to apply for their allocations based on the idea of assigning a /48 to each 'customer' to provide room for unknown technologies, among other things. I did not wish to endanger that premise, but current language appears to moot that concern.

That's not what it says. It says /48s (or longer) should be individually SWIPped if they're going to be announced. Otherwise there's no reason for the extra clause. 

Blocks in the GRT need to be SWIPped to the announcing party if that's a different organization from the holder of the larger block.
