You mean, by default?  No, because such a default will never be
correct, except (evidently) in your very special use case.

Moreover, the resulting directory will not be version-specific, so it
is wrong even in your case, because the next installation will
overwrite the source tree, and older Emacs binaries will not find
their matching sources.

No other project installs sources, so this would be unusual.
