You seem unconvinceable - have you ever accepted a user request (serious question)? Quotes please.
We always accepted user's requests, when they make sense.
There's obviously not need to "quote" every episode, because if you simply look the the very long AFCAD threads, it's clearly proven that all suggestions are always followed.
Or, the threads about the supposed JFK "texture blurriness", which in fact is not really a problem on a properly set system, but we changed a lot our design methods for later sceneries, so they'll appear sharp even on wrongly setup systems.
Or, the threads about making the reinstall procedure less confusing, which lead to the current version of the Addon Manager, that has a reinstall entirely remade, which should be easier to understand for those that don't read the manuals.
Or, the threads about making the purchase simpler, which lead to the use of a Web page as an alternate way of purchasing products, instead of only using the in-game menu, as it used to be.
The suggestion to improve FS9 trying to replicate what FSX already has as default, instead, doesn't make any sense. If we were trying to to do that, it would mean (and this is just a *partial* list)
10x denser autogen
4x texture resolution
Way more detailed default scenery (cities, roads, rivers, lakes, coastlines, landclasses, etc.)
Dynamic airport vehicles with their own pysical modeling and behaviour
Up to 7 cm/pixel photoreal scenery, instead of 4.8 m/pixel
Advanced textures and material properties
Traffic on roads
Even assuming we would ever be able to recreate those features in FS9 ( which shouldn't be taken for granted, and at WHAT cost ? ), the end result would probably be slower than the real FSX, which makes the whole exercise pointless, because at that point, you could just use FSX instead.
If you decided to use the less capable simulator, that's fine for us, but you just can't pretend to have the same features.
Basically, to use a real-world example, it's as if a Wii user would *demand* support for HD resolution from the developer of his favourite game, just because the same developer has done a PS3/Xbox360 version of the same game that has it.
