What is the practical reason behind power-of-two sized textures?

On one hand, I can understand the Mip-mapping (to be able to half the size recursive). Is there anything else?

I'm just investigating if I have no intention to resize my textured sprites runtime, then I should not be aware of this power-of-two consideration, or still should for some performance/whatever reasons.

Used to be that GPUs required such texture sizes. Then they improved & you could use other sizes, but at a performance penalty. Nowadays those restrictions have been relaxed to the point where you can forget all about it.
