Yesterday's issue was more about time difference and communication.

It happened while many witnesses (including me) sleeping, and we currently do not have a very smooth communication path with steemit dev team so it took a while to get the issues attended. When they started looking at it, fix came quick.

However, your suggestion do have a point that (1) it took too long (for whatever reason) and (2) lots of previous developers are left.

We are currently working on how to resolve this issue by funding/encouraging devs to work on various aspects of steem.
