this commit makes applications that make use of the changed components outside of a plasmashell unable to start

@cblack which ones, for example? I'd expect them to be quite broken anyway, since these components are clearly not designed to be used outside of plasmashell.

https://invent.kde.org/system/kiss/ uses the plasmoidheading

That's pretty sad… Can't it use something from Kirigami instead?

Does it provide a Plasma applet, or is it using PlasmoidHeading in an app? If the latter, it should be ported away from that.
