Compressed Documents Still not Byte Served in 8.5

Carl Tyler asked in the previous post if Domino is still not byte-serving attachments which are compressed.
After checking offline with Carl I did some tests with Domino 8.5.

Here is the result. If you have no compression for an attachment it is byte-served. Else there is no byte-serving!

In general on a Domino Server with DAOS all attachments should have the same encoding and compression.
So from storage best practices point of view enabling compression would make a lot of sense.
But this stands in contrast to having the full functionality for iNotes users downloading attachments.

Sounds like the limitation is in the HTTP back-end code that reads the attachment.
And it is not a new limitation but now more visible and important with DAOS and storage optimization.

So if your user community is running iNotes having compression disabled would make sense.
Sadly you cannot disable compression completely because Notes users always have the compress flag enabled when attaching a document...

What do you think? How important is byte-serving for iNotes with compressed data?

Oh one best practice is to attach as ZIP because this is already compressed and will not be stored compressed so byte-serving works.
