OpenELEC dropped 32bit support in version 6.
What about adding it back?
What is your stance about retro compatibility? Are you going to drop features to maintain a small codebase like OE does, or are you going to take a different path?
At the time OE dropped i386 there were ~7.5k active i386 users, but only ~1.5k had a true 32-bit only CPU (the settings addon was tweaked to collect anonymous stats on this) so the majority could (and most since did) update to a 64-bit build. It was something like 0.003% of the active userbase at the time. It would be an even smaller percentage today.
OE has never been a great distro for recycling old hardware with and LE has no intentions of being different. We're not going to rush back and fill the tiny i386 niche with an official build. We will be thoughtful of long-term direction to avoid bloat when making any changes, but overall, and to quote Dr. Spock: "the needs of the many outweigh the needs of the few" 
That said. Once we've found our operating rhythm and I have some free time I will be rebasing patches and releasing a private LibreELEC 7.0 (Jarvis) community build for the mk1 AppleTV (as I have done in the past under OE) and since this is an i386 build with CrystalHD support it will be relatively straightforward for someone else in the community to figure out the remaining changes needed to create a 32-bit "Generic" image from the same github branch. If someone does the work I'd be happy to merge their PR's so others can self-build their own i386 images.
