Incorrect. Checking the size in the jigdo file:

Image size 15909054464 bytes

Packages are ordered and placed automatically when we build the image
sets. Earlier packages are the key ones that we must have (installer,
base system, etc.). Beyond that, we don't have much information to go
on to work out ordering automatically. So we sort by popularity
contest and dependency order, and fill media as much as possible. (In
fact, the algorithm actually runs until it has *over* filled the media
then backs out the last package added.)

In the case of this weekly 16G image build, the last few packages
added look like:

If you care about spyder fitting on the 16G media so much, try getting
more popcon votes for it.
