The sequence field is special-cased early on in read_group (_raw): if
the caller requests the aggregation of ``sequence`` that request is
ignored:
if fspec == 'sequence':
continue
This was added a long time ago, probably due to the special-ish status
of `sequence` (summing sequence number doesn't really make much
sense).
The issue is that it's also possible to request ordering by
`sequence`, which requires `sequence` to be one of the aggregated
fields. This is checked in `_read_group_prepare` and triggers a
warning.
This leads to an inconsistent behavior, where the user requests
aggregating & ordering by `sequence`, we remove it from the aggregated
fields, then warn that they didn't aggregate on the field.
Make the behavior consistent by also ignoring requests to order by
`sequence`.
