Not a limit as small as Google set, and not a limit added overnight without any previous announcement or grace period. If you want to limit storing data in names of blank files, you could say “blank files, files smaller than 1024 bytes, and folders are counted as 1024 bytes for quota purposes”. A minimum billable size seems fair to me, and there is prior art (e.g. AWS S3 has minimum sizes for some storage classes).
