   @JohnDietrich-Pepper I see the issue.. When implementing this fix in #26429 , we didn't consider the case where values are expected to terminate early, only how to deal with interim values.
   
   I wonder if there's some middle ground here? For instance, automatically interpolating zeros until the last defined value, and then leaving the rest null? This would ensure continuous series, but also make sure they terminate when expected. While I understand the problem described in this issue, the problem described in #21093 is IMO also quite problematic, and likely more common than this one..
