Yes, I guess you could make it a native package. The question you should ask yourself isn't whether this is only available for Ubuntu, though, but if you really want to upload the WHOLE source code every time you make a change, even if only to the packaging. The separation of upstream code and packaging code is very helpful. Native packages have their place when there is essentially no upstream code and the core of the package is in the packaging code (the stuff under debian/)
Sorry for the delay in response.
