I had considered to do that, but in terms of "expected API", I would expect that method to return the _current_ issue title.

In essence, this more or less asks for a new Issue Introspection API that's not about saved values, but about the current issue form input instead.  The latter could probably extend the former or have the same interface...

But that would need some more analysis + planning. This behavior uses form values already, only that call to getIssueTitle() is an outlier.
