> Performance looks like a total non-issue for this use case.
The presentation brings up performance as one of the problems with the D-Bus though, so it seems like it is an issue.

it's hard to say, for most D-Bus taks perf. is an absolute non issues, but still you have bus-1 and all kind of tries to make D-Bus perform faster, reason is there are edge cases where it matters
and even if the marshaling speed might not matter the size can, like if something goes really wrong and tens of thousand of system events get spammed the difference between the memory usage of in-flight messages of a compact format vs. json can make the difference between memory pressure effectively killing your server and you recovering reliable
though what is an open question is how relevant that is in pracive
and that is quite hard to say without inside information for companies running systems where such a thing could happen on a scale where such a thing does happen (e.g. google)

Given how central this is going to be why would you skip the tiny bit of extra work needed to use a binary format?
