Yup, you're right - sorry I got confused about this, I was looking at my most current 3DM code which behaves like I was describing but that's something I had changed just after the MoI 3.0 release. So the next version of MoI is set to behave like I was describing (MoI v4 will write a Rhino v5 3DM if it opened a v5 3DM) but MoI v3 does only write out Rhino v4 3DM files.

Well, this is something that you can control - if you need to edit the style/layer list and need to preserve layer material transfer to and from Rhino, do not edit the styles in MoI, edit in Rhino and then you should be ok.
Another way that could work for you would be to set up materials for rendering more at the end of your process after you've completed the models rather than doing it early on.
