reMarkable still work really hard to force you into a subscription - or at least into using their very bad, non-zero knowledge cloud service. ... I don't know why but it is not obvious why this would be for the benefit of the user.
I own a reMarkable 2, but I fill it via RCU [1]. I will absolutely not buy into yet another opaque cloud offering in 2025.
edit: The project you linked looks interesting, though!
