Dear maintainer(s),

I noticed that package science-viewing-dev recommends
libqwtplot3d-qt5-dev, which is currently not available in unstable.

See:

- https://tracker.debian.org/pkg/libqwtplot3d-qt5-dev

It was removed from unstable in April 2026. It says:

"ROM; Qt5; leaf pkg"

I think that it should not be recommended anymore. I don't see the
equivalent for Qt6 (I've checked at package level, not files level); but
I see that science-viewing-dev is based on Qt5 and not yet Qt6 anyway.

Thank you for your time,
