I don't know.

On the one hand I don't feel very strongly about this change, and I have
no intention to block it (because in most cases I do actually increase
the value anyway). I wonder if those with small systems will be happy
about it, though.

But on the other hand it feels a bit weird that we increase this one
value and leave all the other (also very conservative) defaults alone.
