It's documented to prevent the state-preserving behaviour of interrogating param() to see if similarly-named parameters are present in the query.

That's actually what it *should* do as far as I'm concerned, so the documentation is correct from that point of view.

The problem is that it doesn't do that. At all.

If it is deemed useful to have a flag to disable .cgifields from being created while preserving as much stickyness as required, that's fine, but it shouldn't be called nosticky.
