I know what they do, but why do we need it in the defconfig? This is not
a product defconfig, just in case you mirrored downstream patches.

Best regards,

Hi Krzysztof,

Thank you for reviewing this patch.

We believe these defconfigs serve as a generic framework rather than 
being tied to specific product features. Therefore, we have enabled them 
in the defconfig to ensure the end-to-end feature is available in the 
pristine upstream build. However, if you think this would introduce 
overhead for other products, we will exclude this patch in the next 
revision.

Best regards,

Manaf

No...

They are tied to specific products.

Why would we care about this end-to-end feature?

I just did not see here any explanation why this should be added. I
don't need to come with extensive disagreement, because by default we do
not enable everything. We enable only some things because of some
reason. And that's why you have commit msg...

Best regards,
Krzysztof
