Sealing the stock spoke rims for tubeless: what the Moto365 piece says, and what your dealer said

Spent my chai break on the Moto365 piece about sealing spoked rims for tubeless, and it matches what keeps coming up here: plenty of us would love to tape or goo the stock 450 rims and be done with tubes before a Spiti run.

The official position is drier. Michelin's own tyre guidance says a spoked rim is tube type because the spokes pierce the rim and those holes mean no seal, which is why they want a rim band protecting the tube. Royal Enfield's answer was not sealant either. They announced a separate wire spoked tubeless wheel set for the Himalayan 450.

So, honest hands up. Anyone here running sealed stock rims? Year, variant, kilometres please, and whether pressure held through a monsoon. And if you raised it at service, I want to know how that conversation actually went.
