:) its a place holder, haven't gotten around to filling it in. 
The setters are used in qof and I think in gnotime.

Yep, that's the idea.

Yes.

Heh. 

I've converted most things to use QofEntity; I was planing on converting
most things to actually use QofInstance (so that they would all have a
common setter for the KVP tree, and some other common items.)  Prices
stick out like a sore thumb, and would need a major overhaul.  There
are other odds-n-ends, such as currencies.

I was planning on adding reference counting to QofInstance. ... 

I was planing on changing gnc-event to send out references to entities 
and not to guids .... 

Since my whiz-bang SQL backend requires the setters, I was holding off
till then ...
