Hmmm, that's not close to what I'm getting. I used:
C:\ZIP>exiftool -tagsfromfile DSE_5463.nef -r -overwrite_original -ext JPG C:/ZIP/new.jpg
To list all of the meta data in each image, I used:
exiftool -a -u -g1 new.jpg > new.txt
I'm not sure how you counted the fields; obviously the preview images embedded within the NEF are not going to be copied over. Did you allow for that?
Your concerns about the impact of the metadata on the file size are very reasonable, especially if publishing 50-60KBytes images. However, I personally don't think that deleting ALL of the meta data is the right solution. Personally, I'd prefer to define a core set of basic fields; retain those and strip the rest. Off the top of my head... DateTimeOriginal, Camera, Lens, Shutter, Aperture, Copyright. Maybe location and GPS data.
It seems to me that the classic Save for Web tends to throw out the baby with the bathwater
