"how would this impact them? just use figma as usual i would assume"
Since designers share files, whether at the same time, or at later date, if you have someone on the team who is fully taking advantage of all the features, like the new variables, conditional logics, etc.., and you're not quite up to speed, you may not be able to do your job effectively or may mess up what others have done.
Understanding abstractions / reference / inheritance is a skill that developers take for granted. But for non-technical folks, it takes time. Many struggle for a very long time.
Designing a user interface of all things is a technical job, and non-technical folks who are asked to do that should probably study those things to do their jobs well.

looking forward to giving this a spin, our design team tends to go the iterative artboard style with everything...so sussing out values can be a pain
