Sure. I've seen such code code convert

To: [email protected]
To: [email protected]

into

To: [email protected], [email protected]

I don't think it's a problem. The former is illegal to start with IIRC, 
so forwarding it unchanged is just as illegal as forwarding it changed.

I can't, right now, remember seeing problems caused by such code. I'm 
sure there are some, for example with non-standard X- fields.
