Really? 93kb of code is lightweight? Yeah I know it gzips smaller, but that's still not what I'd call "ligthweight". It's not bloated, but it's certainly not a micro-lib.

I think this might miss the point. If you're just writing code on sites, sure, consider jQuery. But if you're creating a library or framework that thousands of others may use, your decision to pick jQuery is making that choice for THEM, which means you should think about it a lot more closely.
It's not then about whether you might like it "next time", but whether the people using your lib/framework will likely need jQuery. That decision should not be made glibly or lightly.
Especially if you're only using a small portion of that 93kb of jQuery, and could just "do it yourself".
