Odin is extremely well known to every human being who keeps up on programming language development, along with Zig, Nim, D, Jai, V, Crystal, Carbon, and others. "programming topics" isn't relevant.
I keep up with PL development, and I am only vaguely aware of Odin (and same for Jai and V).
(But this isn’t the point: lots of programmers know about relatively obscure thing, but that does not itself make them notable. Notability is a well-defined property on Wikipedia.)
There are probably thousands of JavaScript packages on NPM that are more well-known than Odin, that doesn't mean they deserve their own Wikipedia page.
You make it sound like you're confusing popularity with notability.
Unlike Jai and V, Odin has been in commercial use(JangaFX) for years now with several high performance computing products written entirely in Odin and the customers of JangaFX includes several AAA video game and VFX corporations.
A lot of programmers not knowing or the language not being mainstream does not mean that its non-existent.
The Notability of Wikipedia is just the involved admin's opinionated bias. As simple as that. Its always been like that and it'll probably always be like that as Wikipedia seems like it isn't are capable of operating while changing that.
Notability is a qualified state on Wikipedia, as both TFA and Wikipedia itself document.
One of the qualifications is having third-party sources document the subject, where those third-party sources are themselves notable and reputable (in the subject area). A company’s statement that it uses a programming language might be factual, but that doesn’t necessarily make it notable.
(To be clear: I was only vaguely aware of Odin, and I have no idea who/what JangaFX. But that isn’t dispositive.)
To be clear, I was not talking about Odin specifically. This is about notability in general.
>where those third-party sources are themselves notable and reputable (in the subject area)
this is where the bias kicks in. It would be great if Wikipedia's notability goes "All youtube sources are not reliable" but instead its always phrased like "Some Youtube sources are not reliable" and what qualifies as this "some" is usually decided by the personal bias of the admins.

You can read the policy yourself[1]. It doesn’t seem unreasonable to me at all.
It does not seem unreasonable to me as well and I do not recall stating that being the case.
I only mentioned the YouTube scenario, but that's pretty much the case for almost everything. I'll repeat it again: it all boils down to the personal bias of the admins, and you seem to agree with that as well.
