No.

I understand you're saying that's how it works, but:

  1. From a usability standpoint, it's just crazy that messages I've
     read become unread when I ask the summary to update with `M-g'.
     What possible purpose could that serve?

  2. After the server times out and says goodbye, nnimap often fails
     to re-establish the connection until after *two* tries.  The
     result, apparently, is that even pressing `q' sometimes drops
     marks because flag synchronization fails and there's no retry.

Then you should consider sending them when `M-g' is done.
