Why is the DeepStream Triton image running on Focal?

I tried copying the Triton libraries from the DS 6 triton image to the base image, but I’m getting the following error:

libtriton_tensorflow1.so: /lib/x86_64-linux-gnu/libm.so.6: version GLIBC_2.29’ not found`

I tracked it down to being caused by Triton being compiled on Focal with a higher libc6 version, while the devel and base images run on Bionic with libc6 version 2.27. First, I don’t understand why. Given the enormous size of the triton image, it’s impossible to use it in production, but that’s fine since there is a base image. Then, my question is why on earth is the triton image not based on Bionic, or why not finally upgrade to Focal for devel and base? Does this mean that the dependencies listed on the DeepStream Quick Start page are meaningless? Could Nvidia perhaps share the Dockerfile for the triton image? If so, everyone could first of all compile it with the right libc6 version and then just customize it with the needed backends.
