Can you describe what a Locoed callback is in relation to Alien callback
machinery? Does the Locoed callback come in through thunkEntry or by
another route?

The build directly names break the naming convention. Since the VMs below
are Spur perhaps we should call them pharo.cog.spur.lowcode? e.g. when I
build immutability VMs I call the directory e.g.
squeak.cog.spur.immutability. So maybe we can use some convention like
dialect.[sista|cog|stack].[spur|v3].[option1+...optionN]. Or, if lowcode
always implies Sista support then pharo.lowcode.spur would work.
