If inheriting, we should use the regular inherit procedure, like this:

(package
  (inherit dragonfly-reverb)
  ...)

package/inherit is for special cases related to grafting and replacement
packages. [0]

Anyways, it looks like the inherited fields are build-system,
native-inputs, and arguments. Is the idea that there is some build
complication common to the LV2 plugins that we don't want to copy
around? Maybe we could make a build system for them.

Does it work to inherit the custom install phase from dragonfly-reverb?
It seems like the install-file procedures would not apply here.

What do you think? Sorry if I've missed something.
