My concern is that once we extend this mechanism so that you describe
commands separate from the menus and toolbars that they are found in, and
maybe when we add a way to map keyboard shortcuts to commands, disabling
a toolbar or menu simply won't work, and it'll confuse authors.
i.e. I'm hoping we eventually get to a system like:
<command id="copy" label="Copy" onclick="copy()">
<command id="cut" label="Cut" onclick="cut()">
<command id="paste" label="Paste" onclick="paste()">
<accesskey command="copy" key="meta c">
<accesskey command="cut" key="meta x">
<accesskey command="paste" key="meta v">
...and so on. But now what do you do if copy/cut/paste aren't relevant? If
you disable the menus you'll miss the access keys, and you might disable
items you don't want to disable. What you really want to do is disable the
actual commands, and have that automatically disable everything else.
