Comment (by lukeplant):
Just to add to what Julian said:
The alternatives (not using selected_related or limiting to 1 etc) could
just as easily cause 'silly' performance problems where hundreds of
queries are executed instead of one. This would make other people just as
unhappy (or the same people unhappy in different ways). What is more, this
change would be a regression for lots of people. Whether or not 5 is the
best default doesn't matter - it is the number we have picked and you can
override the behaviour. See Jacob's comment on #9554.
