Yes. To use a tool you may need first invest time to learn it. And yes it's 
a trade-off. But:

1. In case of plain memory management PBSP present exactly the same semantic 
as any existent solution. So we could expect the "ordinary" user to be 
familiar with it and do not require time to learn how to use it.
2.  Above also imply that it shouldn't be that difficult to make one more 
step to learn about possibilities of configuring it's behavior.
3. Resource management tasks are quite wide-spread. So whatever time you 
spend getting hold of PBSP the time saving of writing specific simple 
policies will overcome it. So the trade-off is quite reasonable IMO.
