Yes, please. This is an essential changed. However, five operations per block seems a little small (although, 5 is better than nothing is 10 isn't agreeable). I would preferably prefer to see this increased to ten. Specifically, this would benefit Steem Engine greatly as well as the airdrop bot that I have created which gets around this limitation.
Furthermore, can we please increase the limit of 2000 characters for a custom JSON operation for Jussi backed nodes? I would ideally like to see this increased to 10000 characters to make life a little easier from a development perspective.
