I don't think it is a good idea to have different information in different
formats. I'm with Robert; *don't* do that. If you want to suppress the other
ones in text format, do it in the others too. One idea is to add them only if
we prefer the VERBOSE output.

But the latter is more clear than the former.

There are nodes that don't read or write blocks. If we go this way, we need to
document this behavior.
