That's ok for a small game, but not for applications that grow 
over time or projects where the requirement spec is written (and 
continually added to) by customers. But for enthusiast projects, 
that can work.

Many open source projects (and also some commercial ones) work ok 
for small datasets, but tank when you increase the dataset. So 
"match and mix" basically means use it for prototyping, but 
do-not-rely-on-it-if-you-can-avoid-it.

Switching to ARC looks more attractive, scales better and the 
overhead is more evenly distributed. But it probably won't happen.
