Pretty much this. Openfire for instance only recently had XEP-0136 implemented across the board on the server side. In the meanwhile I couldn't find a single client with decent support for chat archiving (XEP-0136) on the client side. Not one (and I really looked).
Hi Dave, firstly thanks for all the hard work on Openfire over the years, very much appreciated.
Secondly regarding XEP-0136 support in OF. I did state that Openfire has only recently had 'XEP-0136 implemented across the board'.
Whilst the Open Archive plugin which provided support is a fine piece of work it was an incomplete implementation with only 1-to-1 chats (no group chat support).
I worked on merging the monitoring and open archive plugins to provide support for both MUC and 1-to-1 using XEP-0136. That work was only fully finished a couple years ago in 2013 so think my comment's still accurate.
