04/10/2019, 7:39 PMUnhydrated: "Pretty much what you read from the file"
Hydrated: "Anything that looks like a reference to something else (another target, a file on disk, ...) is a pointer to, or somehow references, that actual thing"
So in options parsing (where I don't think we use this terminology) an unhydrated option may be a "FromFile(/some/file)" and a hydrated option may be "ignore_errors=True" after that file is read

04/10/2019, 8:05 PMthe general "hydrated" vs "unhydrated" concept is a spectrum from "expensive to compute" to "cheap to compute", respectively

04/10/2019, 8:08 PMi'm not attached to the terminology... as 4535 mentions, these APIs are all temporary, and you almost certainly don't want to include anything about hydration in the name of your most commonly used object type (ie, Target)
