As far as I know the process it to submit patches to hack...@suckless.org, where you can get some feedback and make improvements. On such a simple patch there is just not much to say. Then here https://suckless.org/wiki/ are instruction how to add a patch to the wiki. I'm sure it'll be accepted.
I think most suckless tools are considerd complete and only bugfixes get commited, anything else goes into the wiki patches. And yes, people usually won't go out of their way to comment on a feature that they won't use. Especially if it's tabbed, which I think it's safe to say is much less popular that dwm, st or dmenu.
