I have found an easier way!
XWikiDocument#getDocumentArchive() can be set to call loadDocumentArchive(XWikiContext)
with an
XWikiContext from the ExecutionContext, gotten by way of either XWikiDocument#getContext()
or
XWikiDocument#getXWikiContext()
WDYT?

Based on the response, I am amending the proposal to
add
doc.XWikiDocument.getPreviousVersion(XWikiContext) in case
future development in the old core finds it useful.
api.Document.getPreviousVersion() will be redirected to the new
method.
WDYT?

I did some find-grepping and it seems that getPreviousVersion is not used anywhere
in platform, watch, xoffice, xeclipse, or workspaces.
I don't see the reasoning for having no logic in the API and I hate to add methods
to XWikiDocument but another option is to add a method
XWikiDocument.getPreviousVersion(XWikiContext)

api.Document.getPreviousVersion()

First, the API is not usually available inside the core, and it
shouldn't since actually this is not a service API, but a public
scripting API.
Second, going to the API is an unneeded roundtrip, since the API should
not contain any logic, it should just forward the call to the internal
method, which is again XWikiDocument.getPreviousVersion.
Third, the API might actually disappear in the future, once we move to
the 2.0 model and add @Security and @Access annotations to it to mark
public (scriptable) API methods and their associated access rights
requirements. > My rationale is that we should use public api
