which algorithm do we use for copying buffer sources in dictionaries?

given 
<https://github.com/w3c/webappsec-credential-management/issues/128#issuecomment-427607200>, 
do we use the shorter..

`<dfn>create a copy of any buffer sources' data</dfn>`

..one, or the..

`<dfn>create a deep copy including any buffer sources</dfn>`

..one?

Plus, what is the rationale for preferring one over the other?
