Simpler code for files added to the themes directory is

<?php include (get_template_directory() . "/extracode.php"); ?>

My themes functions.php file is only includes like the above (has no
actual code). Even include an additional file for user custom code
(filename zz_extra_functions.php) so it's easy for theme users to add
custom code to the functions.php file and not have to edit the
functions.php file everytime there's a theme update, just have to not
update that file.

Use the same idea for custom widgets as well for when a text widget
won't work.

Since my theme has so many features built in when a feature isn't used
the include file isn't loaded (based on options selected by the user)
reducing the amount of code loaded. For example have the option of
using 6 montization methods built in (AdSense, Chitika etc...) if the
user doesn't use those ad networks the code is never loaded.

Thousands of theme users, no issues so far with this approach.
