How is this an improvement? All this information is needed to understand why accesses are considered racy.

In mhp.ml these exact conditions are already used to not show empty sets. This just means we don't print mhp:{} without anything in it.
We also don't print empty locksets etc. Everything we analyze and print for accesses is what we have for why access are not racy, i.e. information that can rule something out. If we don't have any excluding information (e.g. no locks), then we don't print that we don't know it. If we printed everything we didn't know, we'd have to print complete states.

Ok, for must-joined I guess this holds.
An empty created set is very strong information though (no information would be top).

If the created set is empty, we're already single-threaded and that's already reflected by the thread flag.

I'm not sure that's true: The created set is relative to the things the current thread created: We may be in a multi-threaded setting and I may not be the main thread but unique. Then an empty created set means that none of my children can be created yet.

Looks good by me. With dbg.full-output all the old output is retained now.
The splitting up of mhp:{...} in accesses I would leave for a separate PR because it's more than just show/pretty/printXml changes. Unless we want it to be like thread:{tid=...; created={...}}, which would be the case since the created thread set is also in the threadid analysis domain. Allowing one analysis to nicely output two components into accesses probably requires some MCPAccess changes.
