Is there any idea as to how often the backfill-date will be changed?

I am working on a new function in the SafeGraphR package that will return the filepath of the patterns or normalization_stats file that a particular date’s data is stored in. For the new backfill data, files are stored in patterns_backfill, followed by nested folders for the date the backfill was performed on, followed by the normal file structure you’d find in patterns.

Is there any idea as to how often the backfill-date will be changed? Or at least for the near future can I assume it will remain 2020/12/14/21 for both patterns_backfill and normalization_stats_backfill?

Thank you!
