It is a two-edged sword. Downside is that a longer limit also invites
deeply nested loops and conditionals, which I am sure will be used as
argument against raising it.

Feel free to submit a patch to raise the limit to 100; I'll be more
than happy to give it an enthusiastic Reviewed-by:. My personal desire
for conflict isn't strong enough to submit it myself, though.
