Review comment:
I agree. However, this might be more limited. E.g. one could have a more
than one resolver per type, each of which can only resolve a subset, or
alternatively one could want to resolve more than one type (or any type), e.g.
a proxying resolver.

> There are a lot of places (e.g. *ParDoTranslation#getParDoPayload*) which
> effectively call *Environments#createOrGetDefaultEnvironment* which causes
> [artifacts to be
> computed|https://github.com/apache/beam/blob/fc6cef9972780ca6b7525d4aadd65a8344221f1b/runners/core-construction-java/src/main/java/org/apache/beam/runners/core/construction/Environments.java#L114].
> This leads to zipping directories for non-jar dependencies.
> Similar problems may exist for Python/Go.
