Every implementation and basically just one implementation.
Bookmarks based on 0049 are widely implemented. Bookmarks based on the
recommended PEP are implemented in just one (two~ish) clients.

The one and a half implementations based on PEP both messed up:

XEP-0048 seems clear enough to me. But 0223 isn’t clear and you can’t
implement 48 w/o 223. (See the link above)

At this point I wouldn't recommend advancing this XEP.
XEP-0048 based on XEP-0049 has big problems with multi client
environments and long standing sessions. (Usually clients fetch
bookmarks once at connect. Long standing sessions then increase the
time bookmarks go w/o being refreshed)
It is unclear due to the lack of implementation that PEP sufficiently
solves the multi client problems (The problem on whether it is better
to put one bookmark in an item or multiple that was raised already in
It feels a bit sad that we aren't able to advance a XEP that is widely
deployed (in a way) but I think it is just too late. If we had this
discussion five years ago I would have happily advanced a version
based purely on 49. But right know it is stuck in a limbo between the
no longer suitable 49 and the unfinished 223.
