Oddly enough, all those approaches are current as far as Jeppesen is concerned. For example, Blackpool RNAV (GNSS) RWY 28, is current on this nav revision cycle and had an original publish date of 24-Aug-07. Typically all the FMS and GPS units maintained through Jeppesen navdata updates would also show it as current. Any operator flying into those airports would expect those approaches to be available today.
The fact that the publish date is after the so-called end to the trial period would imply that we are talking about two different things.
In the US and Canada each RNAV plate typically offers three different limits: the LPV for which WAAS is required, and the VNAV and LNAV which are considered non-precision approaches and do not require WAAS. Waiting for WAAS capability from EGNOS before putting your toe into the pool of RNAV approaches seems like grasping at yet another straw to justify Brit intransigence.
