  | its true, though it doesn't necessarily have to be that way
  | (view models (or even bff) if done properly)
  | 
  | speaking from experience, i think the big issue is how will
  | your dev team be structured... will android/ios people be able
  | to write idiomatic rust (or whatever language) or should that
  | core be a completely separate team? now you cant just hire any
  | dev, they need to understand how it's going to be used by
  | multiple client languages specific to that cross-platform
  | system
  | 
  | though this framework looks like its pre-baking the
  | architecture which means it probably wont look idiomatic from
  | the client-side, so now your hiring for ui needs to take that
  | into account... and now you have multiple teams that need to
  | communicate adding overhead.
  | 
  | using cross-platform sounds simple and easy in the beginning
  | but its a big commitment with multiple facets
  | 
  | i'm not sure what the real answer is... my guess is "it
  | depends: what are you actually trying to do?"
