Dual Extruder cooling fan numbering inconsistent with Luban config

[bertpig]

The Luban dual extruder definitions set machine_extruder_cooling_fan_number to 0 and 1 for extruders 0 and 1 respectively. This is consistent across the 150/250/350/J1 dual extruder configurations.

The Cura plugin sets the same configuration value to 0 for both extruders on all printers bar the J1.

Is this intentional, or is it an omission? I'd assume functionality such as "cooling during extruder switch "in Cura would depend on the fans being individually/correctly controllable.

Same Question - threre are some custom configuration found online of people who set "number of cooling fans" to 1 but just on the right extruder in this forum post
