It starts by computing the targets of all groups, and then creates a map of ruleId -> computed-targets-of-said-rules with no answer as a compliance (A)

Then it construct for each rules the ByRuleRuleCompliance (B), but in there it

1. construct a map of ComponentName, Seq[NodeId, ComponentStatusReports]
2. use this map to convert to Seq of ByRuleComponentCompliance (without using the map property, could have been a seq)
3. and in the conversion, it converts a List[NodeId, ValueReports] to a Map[NodeId, List[NodeId, ValueReports]], where it sorts the list by componentName, then takes the value of them, rather than using lightweight version of the list

finally, it concatenates A and B

I'm quite convinced that nothing from A remains after this operation
