>> is about 80% feature parity, and is around 17k lines of code

You make a fair point that a basic framework can be expressed with much less code.

And that the remaining 20% probably contains more edge cases with proportionally more code.

But do you think the last 20% will eventually make up anywhere near 233k lines of code?

The real save here comes from rewriting: seeing all the common denominators and knowing what's ahead.
