SWUpdate is still the most widely requested option from users of TI K3 SoC. Its a more versatile than RAUC as it provides flexibility wrt image level vs file vs block level updates. AFAIK, Both RAUC and SWUpdate are equally powerfully and well established. Could you help me understand why RAUC is more established than SWUpdate? AGL seems to be on OSTree. OpenWRT, CIP is SWUPdate. Buildroot supports both (default is SWUpdate), so there isnt a common theme. Though SWUpdate seems more common in industrial focused distro space as far as my knowledge goes. Mender is a different story though, its open source but has commercial element to it. And at least K3 based beagle devices are already supported via mender.io [1].
