I don't want to store things in the Index. I want to store it in
something that I as  a developer can think of as a "persistent data
store". An abstract place where I can shovel data into and later
search and retrieve it, and be confident that the data is not lost if
the user upgrades her distribution or what ever.

Therefore the Record metaphor makes good sense to me.

Sure. I am not opposing a deprecation or removal of the Files.Create
(and friends) API of Tracker. Just pointing out the features they
provide are in fact useful.
