Is there a way to increase the upper limit to iCloud storage space? I see here (bold my own):

With Apple One, you can choose a subscription plan that includes 50GB, 200GB or 2TB of iCloud storage. If you need more iCloud storage, you can buy more for a total of up to 4TB.

This seems to mean for people with more than 4TB of data (e.g. someone with lots of family videos, or a hobby photographer), there's simply no way to store it all in iCloud (without creating separate dummy accounts). Is there any way?
For reference, Google Drive goes up to 30TB
Before Apple One introduced 4TB iCloud storage plans, the limit was 2TB. There was no way to increase the limit past that biggest tier, and likewise now with the 4TB tier — there's no tier beyond the largest tier.
This has been a regular complaint of iCloud. The 4TB tier could have been in response to the years of asking for more than 2TB, but of course now we're in the same situation and delaying the inevitable for those of us who store a lot of data in iCloud.
