Technically everything you have written is true. But the proliferation of frameworks is almost a self-reinforcing antipattern.

Or even doing what you need to do.

Certainly, to the extent that a mini-framework is composed of more constraints piled on top of an extant bigger framework, mini-frameworks are, like swimming pools, attractive nuisances. "Hey, look, guys! This is so much simpler!"

> It’s harder to write a framework because it imposes a contract on everything that depends on it.

Judging by what people write and use, I'm not sure this is _exactly_ true. Sure, writing a _good_ framework or library is hard, but people accept piss-poor frameworks, and accept libraries that were designed to work in conjunction with a single framework.

> It’s easier to write a library that is future proofed because it just needs to satisfy its contract.

But the thing is that the library itself defines the contract, and it might be a piss-poor one for many applications.

There is some excellent code out there, and there is a lot of shitty code out there. I think the problem is social; too many people want to write code that is in charge. Now, maybe it's somewhat technical, in that they have used things that are in charge, and they were too big (leading to the mini-framework of the article) or they were otherwise not great, so this leads to yet another framework (cue standards xkcd cartoon) because they realize they need something in charge, but aren't happy with their current options.

And, of course, since the frameworks they know take a kitchen sink mentality, their new framework does as well. (Maybe it's a smaller sink, but everything needed is still shoved in there.) So there are yet more libraries that are tied to yet another framework.

Because writing good libraries that are completely framework independent _can_ be as challenging as writing a good framework. And when someone decides they need a new framework, they are focused on that, and making it work well, and since that drives their thought process, everything else the write gets shoved into the framework.
