>up to 4000
1) I still remember the times of 140 limit

2) I still think the raise to 280 was some kind of hack job in the backend. The 140 limit was because Twitter used to be SMS compatible. There's no reason to limit to exactly doubling up to 280. It could have been 250, 256, 300... The exact 2x140 makes me think their database was still limited to 140 characters, and every new tweet actually linked to 2 database entries.

3) Honestly, I'd say 4000 is a bit much for Twitter, but every complaint on why Twitter discussions devolve into toxicity usually comes to a common denominator of there not being enough space to properly convey what you want to say. So here's hoping this helps a little.
