Two missing features?

I started playing on BGA a couple weeks ago and have been really enjoying it. I haven't subscribed yet but I probably will soon. I'm curious about a couple features that seem to be missing, or maybe I just don't know where to look:

1. Queue with flexible player count. Pretty self explanatory. I can toggle 'flexible' for all other choices, why not this one too? I can even be prompted after queuing to add flexibility to my player count, so why not just include that option from the start?

2. Conceding. Obviously in a multiplayer game, one person conceding early can ruin the experience for the others. But in a 1v1 game, why not allow a player to concede if they are insurmountably far behind?
