remains
The problem is, lcms cannot guess which direction to use.
Let's imagine you have a input profile from RGB to Lab,
and then you connect the colorspace profile after that, finally
you have an output profile implementing Lab -RGB
Which direction to use?
Well, lcms line of reasoning is

very interesting ... thanks
I've just added a check for this via
GetDeviceCaps(printerdc,COLORMGMTCAPS) and am logging it along with
PRINTER_INFO_2.pDriverName in the anonymous stats that one of my comerical
apps use ... it will be interesting to see
