> I'm convinced that half of the jobs listing React are using Svelte or Vue or something, but know they'll get more candidates applying if they hire for react and then just train the person in vue after they start.
Easy to convince yourself of this, but in reality what is the benefit of having to sift through even more applications and waste time to go through the processes just to say "oh by the way we don't use React, we actually use Vue, hope that's ok" and think that the candidate, expecting to be hired to do React will just be like "yeah sure no problem, I actually mastered all the frameworks so it's fine that you lied about what you use."
You're framing "benefit" as it relates to the hiring process. The main benefit of a better framework or tool is that its a better tool.
But as for your points in hiring -
First, there's no need to lie on a job posting. "We use Vue, but we'll hire people with no vue experience. Show us your react chops and we'll train you up".
Doing something like this will get you fewer, but better candidates. If I see a job posting looking for frontend devs where they use SolidJS, I know the team isn't just a feature factory. They're interested and invested in the search for better ways of working. And I know they're given leave to do so by management. Thats a great sign for a good working culture. And from the other side, the kind of people who apply to jobs like that are the sort of people who don't see programming as a 9-5 grind.
I've seen this play itself out a bunch of times. At a startup I worked at many years ago, we took a chance and built our own data pipeline on top of Operational Transform. So all user data was updated live, character by character in our frontend app. It was really cool tech. We worried it'd hurt our ability to hire but it did exactly the opposite. We ended up putting it front and center in our job ads because high quality applicants were super excited by the opportunity to work on cool technology.

Fantasy land.
