Do we have any `uom` users in the chat? A question came up for `postcard-schema` (which affects postcard-rpc):

Should `f32::Acceleration` and `f32::ThermodynamicTemperature` be considered "the same type" from a schema perspective?

* On one hand, on the wire, they are both f32.
* On the other hand, if they have different schemas, postcard-rpc can detect if you send the wrong "unit", e.g. if it accepts `f32::Acceleration` it would refuse to accept a `f32::ThermodynamicTemperature` in its place.
