The problem with relying on a plugin is that every userspace application (currently two that I am aware of: perf and trace-cmd) has to add special-case kvm code to work around our crappy format.
Move the plugins to tools/trace-formats and install them in /lib/modules/$(uname -r)/tracepoint-formats/*.so.
With these patches we at least get back to an event format that is self-describing - no plugin necessary.
There will always be special cases. Look at how trace-cmd formats the kvm_emulate_insn event.
