Sure, but those that are willing to because they're sufficiently excited about the language means you can have a higher confidence in your hires, since they, A. Know what Haskell is, B. Want to learn it, C. Are willing to take a pay cut to be able to get paid to learn/use it. Very high signal to noise I'd wager.

If you're a Java shop, you better be paying higher than market rate if you want to be able to attract good talent, but then you still have to figure out who they are amidst all the mediocre/poor devs, who are interested because of the higher comp. Very low signal to noise.

It seems like a less popular language, that has real business value, helps achieve the thing every company that isn't "hire fast, fire fast" tries to do with their hiring policy. It does mean you can't easily hire people who already know the language, so you have to consider the ramp up time, but I don't think that's nearly as painful as many hiring managers seem to think it is.

Well yeah, it seems you're reiterating that it's great for employers, not for employees. I don't disagree.

Of course if Haskell somehow takes off and all the FANG companies want to hire as many Haskell engineers as they can, then the situation would probably reverse.

I'm more calling out that it's mutually beneficial; the employees choosing that tradeoff are still choosing that tradeoff. The other tradeoff, work for a higher compensated position in a language that they hate, isn't objectively "better", just different.
