Why FroYo Kernel?

I have one question.

Why use the froyo kernel at all?

Upgrading ALL defy/defy+s to the latest (rootable, 1321 or 139 preferred for simpler root) 2.3.6 GB kernel would simplify rom/kernel development for the devs. Since more and more defy+s are in use they can simply drop development for the froyo kernels and focus on the GB kernel, since now all defys, whether the old one or + would be running 2.3.6. Any current devs (if they want to retain current status) would just have to switch to GB kernel support for their rom once and keep it that way.

Because the SOC module (green lens) is compatible only with the Froyo kernel.
Upgrading to the Gingerbread kernel means that the camera will be unusable for those Defys.
Forgot to add: Having a locked bootloader sucks.

So all defys are not equally upgradable to GB (kernel)?

What kinda BS policies are these from Moto? Locked BL they have their reasoning about not wanting users to hard-brick the phones, but what reason to not allow officially updating to GB for ALL defys?

Unfortunately, no, not all Defys can be upgraded to the Gingerbread kernel and still be fully functional (exception being the Greenbread mod). And the devs can't do anything about it because of the locked bootloader.
Regarding Motorola and it's policies - it's all about the money. Outdated phone -> unhappy people -> they buy a new, updated phone -> happy Motorola.

Using Froyo makes sense for those, who want to keep the warranty and have to stick to the highest officialy available version. I had to update because CM roms work only with Froyo upwards.

They buy a new, updated phone from someone else. By keeping the Defy stuck on Froyo they've made a lot of people decide never to buy any product from Motorola again.

This means that there is Froyo source, but not the driver source for the green lens ?

At this moment, if I want to improve my Defy (green lens, original Froyo 2.2.2), what firmware is the best?
It should support everything (3G, 2G, HSDPA, WI-FI, camera for both photos and video recordings, GPS, sensors and so on).

I'm a newbie and for me it's a bit confusing to see a mod called, e.g., "[ICS] CM9 Android 4.0.4 for the Defy (Froyo kernel)" (there are others, this is only the first I've found... )

ICS is ICS, Froyo is Froyo.
What I gain and what I loose with an ICS "Froyo Kernel"?
Is it ICS or Froyo painted with ICS dust ?

Well, I've just upgraded to WIUI 2.4.20 (GB) and now I've GingerBread (2.3.7) full working.
My Defy has a green lens and the camera is working, both for photos and videos.
Have I missed something about the thread?

Are you sure WIUI changed your kernel? ROMs and kernels can play mix'n'match.
