It matters not what Whopity might think.
I agree.
It also doesn't matter what has been discussed in various meeting rooms, nor what the CAA have told Beagle.
What does count is what the regulations state, along with any official guidance material - and nowhere is it currently written that a Night Rating can not be completed within a PPL course of instruction. Therefore any refusal to issue a Licence/Night Rating in such circunstances would be overturned on appeal.
Now it may be that Part-FCL wording is planned to be changed from "shall have completed at least 45 hours of flight instruction in aeroplanes" to "shall have completed at least 45 hours of flight instruction in aeroplanes by day" or similar - but it has not happened yet.
The CAA have promised not to Gold Plate any EASA Regulations so, the least they can do, should they wish to interpret the rules in a more stringent way is to issue an IN informing all in the aviation community of their interpretation and hence requirement.
If they expect the rules to be changed in the future (due to the current discussions mentioned by Beagle) then they should also issue an IN warning of impending change so that Instructors/Students can take that in to account.
