No.
Digikam never was a "core application of KDE", it is a 3rd party application
that happens to use the KDE libraries for its user interface.

But that's just a side-note. ;-)

It is true that it was installed by default in previous openSUSE versions.
And it is still part of the kde_imaging pattern in Factory AFAICS, like before.

No idea at the moment why it wouldn't be installed by default then.
I suppose I have to  a fresh Tumbleweed install.

Did you maybe disable the installation of "recommended" packages?

How exactly did you install Tumbleweed, i.e what image did you use?
