Getting a decoder into the boiler of an Ivatt 2MT might be "interesting" so I can see the logic.
Hornby have included tender pickup for a number of years - certainly the Black 5 has it and I assume the've continued the practice as standard. But they've not exploited this to put the decoder in the tender.
Through wiring has its drawbacks and I notice Bachmann went for a satellite decoder in their 108 ( which also has cost drawbacks) . But it could certainly make a lot of decoder installations much easier
I had a Hornby Ivatt 2MT long ago - it was my first "proper" loco , and I might be tempted even though kettles are not my normal scene
