Should `Chainable#then` avoid data override from external kwargs?

[Rynaro]

fluxus/lib/fluxus/results/chainable.rb

Line 6 in ed71db6

def then(klass, **kwargs)

Is this code susceptible to override before immutable data? Example:

# data = { name: 'Rynaro' }

MyFlow.call!(params).then(MyChainedFlow, { name: 'Neo Rynaro' }) 

Should Results#data be overridden by new flow args? In case of it. Should we let the previous result data be prevalent, and avoid any override action, or raise an error?
