Say the community wants to reduce the size to limit mining centralization, it's not unthinkable that the hashrate majority (which may have to face more competition or harvest less transactions after the change) may oppose to that and then the community is forced to deploy an anti-miner's hardfork (maybe even asic-reset hardfork?) instead of a softfork. Yes, uncontroversial sofforks are easier and less risky to deploy than uncontroversial hardforks, but anti-miner hardforks are not. Not only I don't think it's a good idea for miners to vote on the block size (which is there to control them), I don't even buy the assumption that "we can always just softfork a smallwer size later". If you give something to miners they may not want to give it back later. We could hardfork to 42 M supply and then "just softfork back to 21 M", right? Or what's the same, we could "just softfork supply to 15 M". Such a change would be clearly controversial among miners, so it wouldn't be an uncontroversial softfork anymore. Some of these cases are discussed in BIP99.
