Re: Interactions between max versions and filters
Normally Filters are evaluated before the version counting. There was some issue that was fixed recently that changed this behavior specifically for ColumnPaginationFilters and friend... Lemme see if I can find that.

Hey Christophe:

Sounds like a bug.  My understanding is that the regardless of filters, max
versions should be respected (Yes, we should have a specification but we do
not have one here).
