In my opinion yes, but Chris uses them, so they will stay.  :)
And for Pico compatibility too, of course.

Ah.  No.  You have found a bug.  :)  I never use the indent and
unindent functions, I just add and delete tabs, so I've never
noticed this.

It should.  Mark?  Is this something for you?

No, it can undo a whole series of changes.  Try adding, deleting,
moving the cursor, then adding and deleting some more, and then
undo each of them step by step.

By the way, what you call justifying is called indenting in nano.
Justifying is ^J, it rearranges a paragraph between the current
margins.  At the moment its undo function is special: it can be
undone only rightwaway: see the status line and the help lines.
