Outdated docs on `getNodeKey`?

[jy14898]

I was wondering why the docs mentioned the following under the getNodeKey section:

Note that form fields must not have a name corresponding to forms' DOM properties, e.g. id.

It looks like the note spun out from #129, which suggested a fix, but wasn't taken up. Then at some point, a similar fix got separately applied in #174 but the documentation not updated? Or am I misunderstanding, and the limitation still applies, even with the fix?
