Setting aside any feelings about Musk, ad quality, or even product direction choices like locking down public access...

I'm not sure I agree. My experience of Twitter was that the web app was reasonable and reliable. That reliability seems to me to have been collateral in the transition, a bunch of things broke, famously 2FA for a while, a few redirects broke in the domain switch, the public access lockdown also presented as server errors and 404s for a while until the necessary error states were added, and it has had some spotty downtime. Most of these things are better now than a year ago, but not all, and that's only getting back towards what it was before.

The only notable feature addition I'm aware of is Grok, and again that's pretty debatable.

So I'm interested in what you think has improved. Maybe I'm missing things, but it's not my perception.
