This is the default behavior in Digikam and KPhotoAlbum, the only difference is
that these apps allow changing this behavior. I guess it would make sense to make
it configurable (for the case the image collection is located in an external drive
for example) but this is not my priority yet.

This was added in and the
Kirigami AboutPage component was also added at the same time :)

I asked a few packagers I know and for them, since the packagers can download
the files and put them into the tarball, it should be fine. But they also
said that it would be way better to have it fetched as run time, but it also
means that I will need to do some larger change since currently, the code
expects the files to be there and assert otherwise. I will let you all know
them I figure out an elegant solution.

Fixed using the same hack as in Discover, the current problem is that Kirigami
default sidebar width is too large, but hardcoding a width can break using a
different locale. I believe this will require a discussion in the kirigami and
VDG channel to decide on sane default width, so that applications don't need to
hardcode size that can break on different locales.
