[dev] editing registry.php directly

The registry data is cached. It's only reloaded if the modification  
times of the file in question has changed. So, it really doesn't  
matter where you put it. If you already have a .local file anyway, I  
would place it in there to avoid the extra stat on the additional file.

The main reason for this is because registry.php (and just about every  
other configuration file) is overwritten when upgrading while the  
*.local.php files are not.
