One thing to remember is that processing power is much greater than when GNU Go was written, back in the late 1990's when a typical processor was a 486. Some design decisions were made for weaker processors, such as splitting off the reading code (which tries to decide if a string can be captured by a forced sequence such as a ladder) from the owl code (which very selectively tries to read out life and death). Therefore if GNU Go was written today it would be written differently. Even at level 10, GNU Go is not very strong compared to modern programs. It is something like 10 kyu. So intentionally weakening it by running it at a lower level might be interesting to complete beginners, but I think if someone has been playing for a few months they will want to run it at level 10.
