By the same token, why would I want a pagination script that's doing more things than what I need?

I don't use anything other than MySQL and the only things I require to be paginated are results from a database. My usage is in my directory script and it works perfectly fine for me. I have no desire to change what isn't broken.

However, I can see examples of some instances where someone would require pagination that isn't database dependent. So, it basically comes down to this: People will use what fits their needs and suits their purposes.
