My guess would be if you see, e.g. which lens was used in the converted
file, the makernote field has been copied.
FWIW after conversion to DNG the Exif data does show lens and camera body by
name.

Ken,
Yes, as I've written in response to your original message, - "Makernote"
field needs to be understood by the software that works with the image.
Typically, good software, even if it doesn't understand that field, should
leave those fields in EXIF intact, just carrying it over when saving a new
or edited file. This way you can still open that file in a different
software that understands that field (for the required camera).
I don't know how Adobe DNG converter behaves in this respect.
My guess would be if you see, e.g. which lens was used in the converted
file, the makernote field has been copied. (But it is possible that
it gets written to yet another field in a clear-text format. -- Did
someone mention that earlier?)
If you are interested to find out what is in the original file, and which
information is carried over, I'd recommend using e.g. ExifTool:
https://www.scantips.com/lights/exif.html , looking at the file
before and after DNG conversion.

Just got a Tim Grey Newsletter in which he explains that while using the
Adobe DNG converter will retain the original pixel data from the original
capture, there are some 'private' metadata from the camera that may be
lost. That data would generally relate to unique features of a specific
camera model which would require software from the camera manufacturer to
fully display.
Seems to answer a question I posted awhile back about possibly missing
Exif data relating to my K3 regarding shutter state (time delay,
bracketing etc).
