but as I said to Denis, adapting tonel would be easy, but it would be a cosmetic change when what we actually need is to adapt the structure. Right now Ring2 supports this, but Monticello metadata still doesn’t.
And I prefer to do the real fix, not just the cosmetic one… for me putting a line like this: 

TonelWriter >> methodDefinitionOf: aMethodDefinition
	^ self toSTON: (OrderedDictionary new 
		at: #protocol put: aMethodDefinition category; 

would be a smell, and pointless. 

methodDefinitionOf: aMethodDefinition
	^ self toSTON: (OrderedDictionary new 
		at: #protocol put: aMethodDefinition protocol; 

looks a lot better :)
