I am curious how is InDesign capable of converting from Lab to a
managed
"grayscale"?
InDesign will let you select a grayscale profile in the Print Space
pop-up in the print dialog. So you can convert an entire document into
grayscale. What happens to grayscale images with embedded profiles
would be a good question, but everything else I suspect gets converted
based on the L* channel as determined by the source profile.
You actually have to be careful when specifying black-only objects in
InDesign (or QuarkXPress) and expecting to get black only when
specifying a CMYK profile as destination. InDesign will take objects
specified with black only and separate them into four-color black if
the Document CMYK profile is not the same as the profile you select in
the Print Space pop-up menu in the print dialog. Scary. Vendors need to
do a better job of exempting black only objects from color management -
currently you need to make sure the source profile of these objects and
the destination profile are the same, so you get a null transform.
