Because they support a lot more features?

I made a similar "framework" in PHP years back as an experiment and it was a couple hundred lines AT MOST.

Not necessarily. For example, some minimal web frameworks actually provide multiple routing strategies because different implementation strategy have tradeoffs.

Not meaning to be pedantic, but supporting multiple routing strategies is textbook ”more features”.

Are they, though? I mean, is it a feature to make something usable? If you have hard performance constraints and you know what routes you need to suppport, a generic but prohibitively expensive routing strategy can prevent you from using the framework.

In your own example, having multiple ways of declaring routing is not required to be considered usable.

So, yes.
