Thanks for the replies Charles.

I see that smart_update() was the secret ingredient to make the subclassing work, thanks for all the effort of the example etc. I've changed my code, but I wouldn't say I was overly delighted with putting prefixes in front of all the functions and attributes as future protection. As I only wanted a handful of attributes off the mi for use in my plugin I'm not sure that any perceived gain is worth the negatives of readability, but at least I now know "how" to do it, thanks.

That set_all_custom_metadata call looks like the special call I was after, thanks. That and confirming I wasn't doing something stupid with the behaviour I was seeing.
