So I'm not opposed to this, but it is a little vague.

What does the "hotpluggable" property really mean?

Is it just a hint to the operating system? (which may or may not be
Linux).

Or is it a direction, "this memory must be able to be hotunplugged"?

I think you're intending the former, ie. a hint, which is probably OK.
But it needs to be documented clearly.

Yes, you've got it right. It's just a hint, not a mandate.

I'm about to send v7 which adds a description of "hotpluggable" in the 
documentation. Hopefully I've explained it well enough there.
