This is just a suggestion, but perhaps, instead of having "Debian Desktop Environment" as an alias for the default without any explanation, perhaps it would be better to restructure the software selection menu to something like:
1. Gnome Desktop Environment(Debian Default) 2. Mate Desktop Environment(Recommended for Accessibility). 3. LXDE(recommended for systems with limited resources) 4. No Desktop Environment(System will be command-line only) Etc., adjusting numbers to accomodate whatever other desktop environments can be installed at that point. And I suggest including the no desktop environment option to simplify things for those who'd rather start with a basic system and handle most software installation manually afterward. Might just be me, but this feels much more self-documenting, informs everyone who doesn't already know what the default is, gives those who need accessibility or are setting things up for accessibility a heads up that the default might not be best, etc. Feel free to forward this to whoever would be in a position to consider and/or implement it.
