> As a Factory, WALFactory should only have one job: creating instances of
> WALProvider.
> However, over the years, it has been a landing place for lots of wal-related
> methods (e.g. constructing readers, WALEntryStream, and more). We want all of
> this to live in the WALProvider.
> We can do this in two steps: have the WALFactory methods invoke the method on
> the WALProvider (handled elsewhere), then here we can replace usage of the
> WALFactory "wrapper methods" with the WALProvider itself.
