Hardfork, really?
Personally, I don't call this fork is a hard fork because there are no serious issues with Ethereum network as the time of DAO hack happened years ago, and the network don't have to fork to solve errors from its technical issues.
This time, the fork is for system upgrading purposes, not to solve issues from losses in the network, and so on.
I think that over more than the last one year, after the fork of Bitcoin Cash from Bitcoin, the crypto world have fallen into
over-using the 'hard-fork' term.It's not good at all because it might mislead crypto enthusiasts to wrong directions, that are far away from original purposes of the upgrade.
Constantinople fork is a consensual hardfork, scheduled.
Instead, I would prefer to use the term
'important upgrade' or
'milestone upgrade' to Constantinople for the event.
People created terms for use, then spread them around.
Sometimes, terms used in misleading direction. That's what I meant.
