That's a double-edged sword though, Linus in particular has a habit of calling out any small annoyances / rough edges of things he uses, especially if for a challenge.
We as (I assume most of us are) experienced self-hosters with a technical background can deal with these for the massive upside of having a free, open source, non-commercial media server, but he'd definitely go in with the 'look at it as if I was a regular user' angle, which likely means a lot of complaints about stuff like client support, potentially a more complex setup for secure remote access, etc.

I still think a LTT video on Jellyfin would likely be a net good, but I'm pretty sure it would include a fair amount of criticism of the less complete / rougher edges of JF, and I'm afraid that might make it pretty unpopular with this same community haha
