Not to mention all the other *config variants, which work in a
similar fashion:

make ARCH=i386 allnoconfig # writes 32-bit all-disabled config into .config
make ARCH=i386 allyesconfig # writes 32-bit all-enabled config into .config
make ARCH=i386 allmodconfig # writes 32-bit all-modules config into .config

make ARCH=x86_64 allnoconfig # writes 64-bit all-disabled config into .config
make ARCH=x86_64 allyesconfig # writes 64-bit all-enabled config into .config
make ARCH=x86_64 allmodconfig # writes 64-bit all-modules config into .config

and i use them in this fashion both as typed commands and in scripts,
and many other kernel developers are using them as well.

So contrary to your claim there's *one dozen* very useful uses of
this 'old' form - with no functional replacement AFAICS.

Thanks,

Ingo
