Ocsigen and ppx

Don’t you know when Ocsigen will work on OCaml 4.06 and use ppx instead of camlp4?

As far as I know, Ocsigen already lets you use ppx for syntax extensions, see Ppx for Eliom and Ppx for Tyxml in the Ocsigen manual. I don’t know about 4.06 compatibility, but I would suppose that you need to give some times for larger projects to adapt to the breaking changes in the just-released 4.06. Using Ocsigen in 4.05 should work.
