Possible missing cp on Artisan's Apron

Is the missing CP on the apron a bug? According to the patterns I recall, When comparing the 4 star artisan crafts with the AF sets:

Hands:
AF nq: 2 cp / 27 control
AF hq: 3 cp / 31 control
Art nq: 2 cp / 29 control
Art hq: 3 cp / 33 control

Shoes:
AF nq: 3 craft / 27 control
AF hq: 3 craft / 31 control
Art nq: 3 craft / 29 control
Art hq: 3 craft / 33 control

Pants:
AF nq: 3 craft / 27 control
AF hq: 3 craft /31 control
Art nq: 3 craft / 29 control
Art hq: 3 craft / 33 control

Chest:
AF nq: 2 cp / 27 control / 81 craft
AF hq: 3 cp / 31 control / 92 craft
Art nq: 0 cp / 29 control / 89 craft
Art hq: 0 cp / 33 control / 101 craft

Theory Art nq: 2 cp / 29 control / X craft (lacking info)
Theory Art hq: 3 cp / 33 control / X + Y craft

I believe they removed it to make it more versatile. You can meld the extra 3 CP on it if you choose to, but if you don't want more CP you can push more crafts instead. That's the reasoning I can see behind it at least, rather than it being a bug.

Perhaps I don't understand but if anything I would argue that it is less versatile. Versatility is to my mind the number of ends I could put it to. By removing the CP and forcing me to choose how I should meld it the item becomes specialized. My choices increased, but the versatility of the item (and my versatility wearing it) have been reduced. Making it usable by all classes increased the versatility, removing the CP did not.
