May I ask what this means?
Drivers for RPi2 and 3 are currently not yet feature complete and stable.
LE10 uses a completely new and different graphics and video decoding stack. For quite some time RPi0-3 had some severe issues (which are mostly solved now) but so far we could do only a very limited amount of testing on RPi2/3 so there might be more bugs lurking.
One of the major missing features on RPi2/3 is GPU accelerated HEVC playback - which means HEVC is practically unusable. Not sure if or when this will be added, it's very tricky and other missing features like deinterlacing (which is also important for RPi4) have higher priority.
We'll look into providing LE10 testbuilds for RPi2/3, if you don't need HEVC these should already be quite usable - and feedback from testers will also help us find bugs.
so long,
Hias
