To be fair. Kobo firmware up to and including v4 is running some truly ancient software, and it was built with a custom toolchain.
FW 5.x has much newer software. It has Python, the latest Qt (the version of Qt in the older FW is truly ancient). And Yocto is basically the industry standard for building firmware these days.
Unfortunately, I do not have a Kobo which can run FW 5, nor do I have Yocto experience.
