only dynamic derivations could produce a non-opaque drvPath. since dynamic derivations are no longer supported we can have drvPath be opaque at all times, simplifying downstream code significantly and making quite a few methods unnecessary. discardOutputPath was only called on drvPath members anyway and thus reduces to a copy, other operations at the very least are no longer recursive. some vestige of dynamic derivations remains in DerivedPathMap though (for now).
