What do you propose exactly?
Hi David. What I mean is that having an optional positional field...
MyEvent Field1 Field2 [Field3] Key1=Value1
... means we cannot ever add more positional fields in the future. For example...
MyEvent Field1 Field2 [Field3] [Field4] Key1=Value1
... would be ambiguous if the third field is Field3 or Field4 since they're both optional. We also could not add new mandatory positional fields...
MyEvent Field1 Field2 Field4 [Field3] Key1=Value1
... because it would be ambiguous if the third field was Field4 with a new version of tor or Field3 with an old one.
I can't really change the "DescriptorID" to a key=value format. So, you think I should just not extend that field and use a new "key=value" for it?
Why not? Does the DescriptorID have equal signs in it? If so then you could also make this be a mandatory positional field with a filler value like 'none' if unavailable.
