Please note that x32 != x86. |

That would undermine my resurrection activities i do on old but gold hardware. |
CONFIG_X86_X32 removal isn't the removal of 32bit support (this is just CONFIG_X86) .
x32 is a hybrid 64bit mode permitting access to x86_64 enhancements but with 32bit points (faster)
As I understand it, it is hardly used _________________

There is not a good reason to do this since x86 is a mature architecture; is not substantially more trouble to support than other, less popular architectures; and is widely used even now. However, if they wanted to do it, they could. Contrast this to x32, which is young, not widely used, and by some accounts, hard to support because of the strange mixed-mode ABI that works like x86 in some places and x86_64 in others. |

To my knowledge it was never even considered ready for deployment, so there is that. _________________ First things first, but not necessarily in that order.
Apologies if I take a while to respond. I'm currently working on the dematerialization circuit for my blue box. |

yup? It takes resource to roll a 32bit and 64bit. Archlinux dropped 32bit last year
How many use 32bit to warrant the infrastructure at distribution level? For Gentoo it is a bit easier as it's almost all from upstream so as long as there are Devs checking the buildability of 32bit packages it will stay as an option. _________________

i've always been amaze by the binary vs source irony.
using source you help the most the poor cpu that need every tweak you could gave it to run faster, but at the cost it's a real pain compile it, well, because it's a poor cpu.
using binary you get generic optimization and bloat where your poor cpu should have the most help you can give it, but you help it a lot when installing a package.
I suppose the i386 binary version are so crappy bloated it's no more worth using it and people with poor cpu prefer some better alternative (like a gentoo fast cpu building optmized and non bloated binary for the poor one).
But what will happen to people without access to a fast cpu to do that if binary distros drop i386 build? |

That just means those volunteers will no longer be building and uploading i386 / i686 (classic 32-bit) packages. Anyone who wants to build for classic 32-bit can still do so, and may even be able to use some of the build scripts provided by Lubuntu to do so (if they wanted to follow Lubuntu instead of Gentoo, or Arch, or Fedora, or ...). |

Since you are presumably on Gentoo, I don't see how this affects you. Gentoo is not Lubuntu. Gentoo's support for x86 is different from other distributions, since you always build locally. As long as upstream projects do not drop support for x86 builds, and Gentoo's ebuilds continue to maintain correct keywords, you can use x86 on Gentoo. |

You should never get your Gentoo installations dirty. Cleaning up later can be time-consuming. |
