libqt4-webkit transitional package not ported from Debian

I tried to install proprietary software which's deb package depends from libqt4-webkit (Rumus, https://www.fxclub.org/software/rumus2/ ) and it cannot be installed without modifying debian/control and repackaging the bianaries; I see that Debian seems to have dropped this transitional package and now it it present only on ARM64: https://packages.debian.org/search?keywords=libqt4-webkit&searchon=names&suite=all&section=all
Why did they drop the transitinal package on all architectures except ARM64? Can Ubuntu port the transitional package to easify life for its users? Should I report this bug to Debian?
