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.
