Well, here's my best shot at finding them so far:
apk search | sed -e 's/-[0-9.]*-r[0-9]*$//g'  \
	-e 's/-[0-9.]*_[a-z0-9]*-r[0-9]*$//g' \
	| grep -ve '-r[0-9][0-9]*$' | xargs apk info -s \
	| grep -B1 '^4096$'

Technically, this lists all packages for which 'installed size' is 4096:
in other words, no contents or one small file.
Some of these are false positives or deliberate transitional packages.

This lists 65 packages, which are as follows:
xf86-video-modesetting-0.9.0-r6

libreoffice-5.0.3.2-r1
xfce4-4.12.0-r0
lua-sql-mysql-2.3.0-r3
opennebula-node-kvm-4.9.80-r0
lua-date-2.1.1-r0

If you strip off the version numbers and send that to 'pkglist',
here's an attempt at eliminating meta/transitional packages:
for pkg in `cat pkglist `; do
	F=`apk info -d $pkg|head -n 2 | tail -n 1`
	case "$F" in
		(*[Mm]eta*|*ummy*|*removed*|*[Ww]rapper*) ;;
		(*) echo $pkg - $F;;
	esac
done

Send the output to a file 'nullpkgs', and I find it's 39 lines long.
Now, looking for the real empties in those:
for f in `cut -d\  -f1 nullpkgs`; do
	apk fetch $f
	tar -tzf $f-* | grep ^.dummy >/dev/null && echo $f >> /tmp/truenulls
	rm -f $f-*.apk
done

That's 39 lines, no false positives there.
At least two of them (abiword-plugins and texlive-full) are metapackages.

So, nullpkgs is the list to look through.
I'm attaching it for the use of package maintainers.
