It's been discussed quite often (and I'm sure it always will be), but Tiny Core is a tool kit. Think of it as a toolbox containing the kernel, busybox, X-Windows, and a few other files. The extensions are simply other tools you can add to your toolbox. In any case, you can do just about anything with the tools provided, but you need to be skilled with them in order to use them effectively.
The basic message is that Tiny Core is absolutely minimal, and you build up from there. You get to make the choice about every application you install. For example, dropbear used to be part of the base, but it no longer is. You are free to install openssh instead and never install dropbear if you are so inclined.
I don't understand why some core developers of TC don't see it yet.
It is outside their scope.
Anyone here is free to build a more "full-featured" distribution using TC as a base, and some have. For the most part, the core developers work on the core and extensions, and this forum is for discussion and support of that work. Tiny Core has improved very rapidly as a result of this focus.
Discussion and support of work beyond the core and extensions, like remasters, is outside this scope (except for the provided announcement board). Specific remasters should host their own forum so they can focus on their specific needs, like Debian, Slackware, and RHEL derivatives do.
