Other than the use of MEGA in patch 17, I'm fine with this now, but would like to leave more time for Eugen and others to comment if they wish. Given timing, I'm afraid this is very unlikely to make the next merge window anyway now, so we have lots of time. Sorry for the delay in my reviewing v2. Pesky covid.
