The Monochrome2DNG utility is intended to streamline using cameras converted to monochrome and avoid artifacts and loss of resolution caused by (now, unnecessary) demosaicking which would otherwise be applied.

It takes input files from cameras that have been converted to monochrome.
It then saves it as "truly" monochrome DNG files, suitable for using with popular converters that support the DNG format (that is to say, almost all of them).
With this
One can turn on automatic "monochrome" recognition and convert only the files from converted cameras (so one can process a large archive that has both color and monochrome files in it quickly, in one pass).
Automatic mosaic pattern suppression is supported (output files will not have 1-pixel grid patterns)
Several formats for output DNG are supported, which allows one to use their RAW converter optimally.
Filter input files by Vendor/Model/Camera serial to process large archives faster.
