I've heard of the tinyfication project, but not paid too much attentions.
I believe it's the wrong side around.
For busybox, patches that produce larger binaries without providing
new functionality are just rejected.
Those that provide new functionality and such create bigger binaries
must have a configuration option for still being able to get the
old small binary.

If you accept patches that make the kernel bigger without a configuration
option to avoid this, any tinyfication effort that tries to make the
kernel small again afterwards is IMHO a noble but lost cause.
