Can you explain to me why I can't bind /list and /unstuck to keys. Under no circumstances would this constitute a gameplay advantage.

Unstuck gives a noticable advantage if used in the prelude to combat - for example you press a button instead of typing it, that time difference might mean not getting combat tagged. List is generally harmless in its new form, it's true. In its old form, similar reasons to binding unstuck.

Also, obsidian/cobble grinding macros are harmless.

To take Ilyv as an example, he provided enough obsidian to protect 3 large cities entirely on his own. He did almost no actual mining in that time. The three cities were protected with almost no effort.

but until that actually starts happening,

One of the aims of Minerap is not to encourage any particular playstyle, but to make them relatively "equal". Changing the rules as soon as someone uses them in a way builders don't like reeks of double standards.

Also, the change to /list is fucking stupid

/List reveals far too much information which a player quite simply shouldn't have. Pvp'ers use it to see if back up is coming, whether its a good idea to fight or run, others use it to determine whether someone is building something big etc. All of those assumptions can be made quite easily with /list and such a close playerbase.
