Yes. I think since at least 3 yerars.

The format is AFAIK documented in CFLite which is open source.

And, reading the file instead of forcing the user to copy it to a Mac,
apply plutil and copy back, is a little user friendlier...

Finally, NIBs are keyed archives. Keyed archives are plists. So a
valid NIB may be a binary plist.
