as with most roles, I think it is negotiable. You have your professional leverage, expected pay and grit. you need to balance these things.

Also, if you can get an equivalent role with less requirements such as being on call, then I guess it is just a question of grabbing it!

I mean, you have oncall, it's just permanent oncall.

Not really. If I don't agree to on-call, I do it on best-effort basis. That is: "Oh, I'm camping with kids without a computer. I'll try to help you as much as I can. Did you try Z after X and Y didn't work? Ok, try it and call me back how it went, I'll try to Google something in the meantime." If that would happen too often (more than 1-2x a year), I would try to improve the process or consider switching my job. And my phone is silent during the night.

I wouldn't call this a permanent on-call, just being responsive.
