The put_get_helper is just something used internally to abbreviate  
the construction of lots of different property maps. However,  
building property maps is pretty trivial: it's just a structure with  
1-3 operations and a couple of free functions. I don't really see the  
need for an expanded framework to help build them.

You might also consider that the BGL is fairly dated and stagnant,  
and in need of some serious TLC. Whether or not property maps  
continue to exist in the same form in future renditions of the  
library is anybody's guess - I'm leaning towards "no".
