What's worth saving from laptop batteries apart from the cells?

As per the heading is there anything worth saving from laptop batteries apart from the cells?

I've got a box full of BMS boards, temp sensors, flat plate cell connectors etc

Is there anything worth keeping for perhaps when building my own batteries or is it all just good for the bin?

I’d say it depends on what’s useful to you personally. If you’re going to build a battery pack, and you know how to wire up those laptop BMS boards, then it would be worth keeping one for that. The laptop boards aren’t useful to me, because I wouldn’t know how to use one. So, if I’m going to build a battery pack, I’ll buy a BMS that is made for DIY pack building to make things easier on myself. The temp sensor can stay with the BMS, if you’re planning to use the BMS. Also, there are some BLF driver designs that have temp monitoring, so could use the laptop temp sensor, I guess. I don’t keep the temp sensors either, because I don’t have temp monitoring in any of my lights.

So basically the temp modules are the only part that could feasibly be used further down the line?

I was thinking maybe the BMS boards might have some special surface mounted high wattage discharge resistors etc

Well, I didn’t think about taking the BMS apart for the components. They probably could be useful, actually. But still, you’d have to have a specific need for the values of the components that you’d get.
