in P3D from 3.4 should not even exist artifices on the cfg file because extensively optimized by LM and also recommend an AF=14 is really gruesome.
Personally I do not have KMEM, but products such as gsx and others where it still exists an addon manager who can affect vital parameters of the configuration file ... I do not think it's a good way to go yet.
You are assuming Addon Manager is doing changes "on its own". This is a common misconception, but it's NOT the case!
In order to have something applied to the .CFG file, the user MUST press the "Save" button, otherwise nothing happens. Without pressing Save, the settings are showing only what will be saved, should you press the "Save" button, not what it's being used now.
In fact, what we are doing with the KMEM installer, is precisely what you are suggesting: streamlining the CFG file by removing a tweak that has been proven to be dangerous ( Poolsize = 0 ), which is the only thing we change automatically while installing.
From what I hear from many people, you concentrating more on the details of how to play the avatar walking in the tower, and you have forgotten the basic things that really need in an airport.
KMEM has everything an airport needs, and what it has more, only added to its development time.
You might have had a point, if we took the same time to do KMEM as, for example, JFK, but in fact, it took more than double amount of time: 2 years instead of 9 months. This is our own decision, which might be correct or not, but its our own, but you cannot say the never seen before features in KMEM were obtained to the detriment of something else.
Other users complained that all our other airports now looks outdated, because they don't look as good as KMEM.
And, KMEM is so detailed, because we listened to users comments about the previous one, KIAH, that it looked too "ordinary".
Incidentally, KIAH is the scenery that has less issues reported, of all the sceneries we ever made so far. And it's the one we are not 100% happy of sales. So, users voted with their wallets and expressed a clear preference against sceneries that are "ordinary" AND "reliable", and we cannot ignore this, so we worked hard on adding details on KMEM, which would really look boring, if we didn't, because it IS boring, even in real life, if wasn't for all the frantic cargo activity.
I'm sorry because you have a product monster like GSX and maybe you get lost in some detail too in airports like this
There are other developers, that present animated flowers in the wind as a selling point of the scenery so, who's deciding when too much detail is really too much ?
