Try it and see, I suppose. My experience of it is that you can read an individual conversation but if you just look at some random person's timeline it will only show you a few tweets before asking you to log in.
Could be desktop. Mobile browsing still seems to trigger demands for the app to be installed followed by login requests, though I just picked a few tweets at random rather than checking systematically.
That specific behavior seems to have gone away when musk culled a whole bunch of microservices a couple weeks back. I know well what you're talking about and it annoyed the hell out of me, but now its gone! For now, on desktop browsers, anyway.
