What growth? Look at the mempool, most of the time it's far from full. Transactions are cheap. It's only when the mempool gets spammed out of nowhere that people cry about bitcoin. Ver and co spam the network to get the big block narrative going and confuse noobs into thinking increase the blocksize is a must now or else we'll die. Bollocks.
Still not a bad thing to go the 2 MB blocks even if currently 1 MB would be sufficient.
In a couple of years it will not be and then we have double the headroom.
In a couple of years we will have lightning network, and if we REALLY need 2MB, we will do it without less risk AND with a lot of other cool things that could be implemented with a hardfork. You are supposed to get maximum consensus in a hardfork and you are supposed to get as much interesting stuff as possible to avoid needing further hardforks.
Hardforking in a matter of a couple of months with software that is clearly not up to bitcoin standards is suicidal and not logical by any means.
