I haven't explicitly asked the community about their stance on this, but I am pretty sure that most people agree the sysop should be able to do those things. I'll do a real survey soon.
On a related note, I have found a way to move and create flow pages as a sysop. I moved user talk:bluedeck/flow to user talk:bluedeck/flow/test with my little exploit. So in all actuality sysops right now can create as many flow boards as they wish and move them wherever they want.
I published this exploit in the local VP a while ago and a global renamer in our community, Wong128hk, I believe, uses this scheme to fulfill rename requests that involve moving flow talks.
