At the risk of repeating myself but the question is about the default
in the absence of additional information.
Or stated differently the user told you to encode to h264 and that
pretty much implies that he wants h264 that works for an UNSPECIFIED
target or ANY target.
like compiling C without extra switches generates a program that
works on ANY reasonable variant of the host platform

whats so hard on that so that we drift of in a discussion about
a-bombs and spaceships (not mass produced items intended to be used by
the general public currently)
We do want ffmpeg to be useable by the general public for genral tasks
the average joe might want to do.
like "hey i want to convert my ogg to mp3, target device huh i want to
share with friends no idea what they or their friends will use it on

Frequently ignored answer#1 FFmpeg bugs should be sent to our bugtracker. User
questions about the command line tools should be sent to the ffmpeg-user ML.
And questions about how to use libav* should be sent to the libav-user ML.
