A recipe can provide several packages, usually one with the same
name as the recipe name, then the -dev, -dbg, -doc ... packages,
but a lot of recipes provide additional packages.

An image recipe defines what packages need to be installed in an
image.

Even if your image requires only a part of the packages that a
recipe provides, all packages will be built and will be visible
in build/buildhistory/packages leading to what you describe above.

On top of that, if you built an image which contains different
packages before or bitbaked single recipes then those would also
be seen in the build/buildhistory/packages tree.
