It's still just looking at one server right? If you have a fleet of webservers, or microservices in containers, ELK or similar seems like a requirement.

There's some basic support for tailing files on remote x86 machines (https://lnav.org/2021/05/03/tailing-remote-files.html). But, again, just small scale stuff.
I use it on my development machine and for going through logs attached to bugs. Those use cases aren't served by something like ELK/splunk/etc.
