So why bothers 3.15+ Linux kernel? Why not use an old kernel e.g. 2.4.x?
2.4.x kernel doesn't have so many new features you want to get rid of here.

You've got to be kidding.  Using 2.4 for a new network-connected device,
today?  With all of its potential security holes that nobody is paying
attention to?  Easier to fork 3.15 and trim it down than to do *that*.
And there *are* a huge number of useful features in 3.15+, not least of
which drivers for current hardware.

So you're saying that the 2.4.x -stable maintainer did a shitty job and
his work is worthless?

There's a difference between maintaining 2.4.x for all the existing
users who can't or won't upgrade, and introducing a *new* product
shipping with 2.4.x.  There's something very wrong if 2.4.x works for
cases that 3.x doesn't; that would be a serious regression.
