It only means they didn't deserve you. I have gone through a few interviews of this nature off late. Given the, timelines(and technology limitations) they give you to complete the assignment and return it to them and managing a day job with family, frankly speaking I had to slog through whole nights for sprints of 3 days. For nearly a month for various interviews.

At the end some companies appreciated it and some just plainly gave a very discouraging feedback.

If you can't appreciate a person who can deliver your requirements with 100% features covered and well tested to the point without wasting any time on clarifications, under crippling timelines- Then clearly you are looking for men from an another planet.

You must just wish those companies all the best and move on. They are ultimately going to hire some career cup scraper any way.
