Bitcoin cash developer: can't mine any block larger than 2 MB

Bitcoin cash developer Amaury Sechet said the network could not mine any blocks larger than 2 MB. The founder of BSV, Roger Ver, has already supported larger blocks to solve possible problems in Bitcoin. Some people think that this is not a big deal. For example, Bitcoinated forum moderator AvatarX claims that BCH can't keep more than 1 MB block even for 30 days, so it is normal for the network to have problems when it exceeds 2 MB. And some people are worried about the limitations of new discoveries or bring new problems.
