If they might be useful, you could add a page with links to examples that don't meet your threshold for full inclusiion. That would probably take a sentence or paragraph to describe the target of the link. -- These are my opinions.

Re: [Linuxptp-devel] [PATCH] Add E2E automotive profile example configs.
I think automotive profile is defined here: https://avnu.org/wp-content/uploads/2014/05/Auto-Ethernet-AVB-Func-Interop-Spec_v1.6.pdf . The document doesn't say anything about transport layer or delay mechanism. So I just took the existing automotive profile and switched it to E2E. This has been practically verified to work on our mobile robots to sync time between several computers and sensors (one of which is considered time master). In mobile robotics, space and weight are limited, so the ability to use a TC-only switch is crucial. Otherwise, the mobile robot behaves very similar to a car in the way that the devices are known a-priori, and the whole system is mainly intended to run as an isolated time domain (i.e. time-consistency between robots is not as crucial as time-consistency inside one robot).
