> Too bad the notion of completed/finished/done software is very weak.

FWLIW, this simple definition suffices for me: software is complete insofar as it requires no changes to do what its maintainers would like to do with it at the current point in time.

"Complete" software frequently changes to "incomplete" as the desires of the maintainer(s) change(s), and may just as quickly revert to "complete" as changes are made.

This definition does not consider the desires of non-maintainers because there's _always_ at least one such person who wants a given pieces of software to do their one weird thing (which the maintainer(s) will not ever add).
