How well does this support random-access queries to the file names and content at a certain revision? Like:

- "Checking out" a specific branch (which can be reasonably slow)

- Query all files and folders in path `/src`

- Query all files and folders in path `/src/*` (and maybe with extra pattern matches)

- Be able to read contents of a file from a certain offset for a certain length

These are similar to file system queries to a working directory
