Neon doesn't actually have a kwin-wayland-backend-hwcomposer package, so renaming is not a solution. apt-pinning seems to be the right approach.

schmeisser added a project: Plasma: Mobile (PM 1.0).

TASK DESCRIPTION

currently when running

  sudo apt upgrade

on Plasma Mobile it will break whenever Neon has a newer version of
Kwin than Plasma Mobile. Correct?

one idea was to use apt-pinning in order to prefer packages from PM
over neon

another is to rename the plugin package like this:

https://packaging.neon.kde.org/kde/kwin.git/tree/debian/control?h=Neon/mobile

Package: kwin-wayland-backend-hwcomposer
Section: libs
Architecture: armel armhf
Depends: ${misc:Depends}, ${shlibs:Depends}
Breaks: kwin-hwcomposer-backend (<< 4:5.3.90+git20150807)
Replaces: kwin-hwcomposer-backend (<< 4:5.3.90+git20150807)
Provides: kwin-wayland-backend
Description: KDE window manager hwcompositor plugin

becomes

Package: kwin-wayland-backend-hwcomposer**-halium**
Section: libs
Architecture: armel armhf
Depends: ${misc:Depends}, ${shlibs:Depends}
