I think you may be being a little harsh on the AIS.
AIC Yellow 336 (60/1999)covers a superset of what used to be in the AIP. In addition, there is even CAP694, if you need even more explanation.

No, I don't believe I am being too harsh. AIC 336 is specifically for NAT flights and covers a lot of information of no value to GA. CAP694 does indeed provide the data but I have yet to see a copy (I presume because you have to buy it) and it is not mandatory material for any ATSU (AIP and AIC's are).
What I am suggesting is that by removing the "Completion of FPL Form" data from both AIC and AIP at the same time it has become quite difficult to get help when you need it. I would have liked to see it remain as an AIC - our copy was well and truly grubby with frequent use.
I phoned our local FBU today to see their reaction on a FPL query. They hadn't heard of CAP694 and could only refer to an out of date Pooleys they found!
