Dropping 32-bit x86 from CI feels like a no-brainer in the current situation. As to deprecating 32-bit x86: the people by far most qualified to judge the "cost/benefit thing" are the regulars who are bearing the cost, i.e. the people who are actually maintaining it. Their opinion should overrule any "but somebody out there might still want to use it". Maintainers, please state your opinion, if any: aye or nay. Richard tells us "the maint overhead is large." Makes me think he's in favour of dropping 32-bit x86. Richard? Peter seems to be reluctant to drop 32-bit ARM at this point. Peter?
