 I'd go even further with that: make “antialiased” one of specific brush
 settings, not the “tool” itself. That way one would be able to have as
 much “pencils” predefined as one sees fit. And all that without
 touching tool tickbox back and forth if needed.

There's a difference between an aliased brush applied with the Brush
tool compared to the same brush applied with the Pencil tool. Try it.

The Pencil tool is important for tasks that require pixel-perfect
retouching, such as icon drawing, as it doesn't do sub-pixel positioning
such as the Brush tool does.

But of course under the hood it's the same paint core with just one
setting changed. But that is true for more tools. Paint tools, as the
user sees them, are solely a user interface thing. They represent a
certain bunch of properties set on the paint core. We could of course
expose all these properties to the user and doing so would allow us to
merge some tools. But actually I think it would be much better if we
would offer more presets to choose from. Instead of merging Pencil and
Paintbrush we should rather offer more variants like a Soft Pencil
that works more like what Liam expects, a Hard Pencil for pixel-pefect
icon retouching, a Crayon, ...

 My reasoning is that for a new user, the difference between brush and 
 pencil
 is not evident from their name or icon. They do pretty much the same thing 
 with
 they only difference being that pencil is not antialiased. The pencil tool is
 nothing like an actual pencil. So, if we want the UI to reflect the actual
 workings of the program, it makes sense to do this.

 The only objection I can think of is if in real-life situation people actually
 use the pencil tool in conjunction with the brush tool in such a way that they
 have a separate settings for each, and the change from one to other a lot. But
 that is what tool presets are for.

If you have a tablet, you can switch tools by reversing the stylus. It's 
meant for brush vs eraser, but someone must be using that for brush vs 
pencil :-)

BTW. Is it possible to assign shortcut to a brush type or tool preset?
Without it presets are only half-usable IMHO.

I agree with that. After all, both these tools are made to scribble on
the canvas with some shapes :).

Not a problem, I think, as far as presets are accessible through
shortcuts.

There's no reason I can see that pencil couldn't just be a predefined
tool preset for painting with an icon on the toolbox, and people be able
to add their own presets to the toolbox and maybe bind them to keys.

The name is a little misleading - I'd expect a pencil to leave a soft
grey stroke that's slightly uneven. Gimp's pencil tool is closer to a
rapidograph-style drawing pen, except it doesn't clog up so easily :-)
