$SITEURL: does it really need to include scheme/host/port?

Of course there is

Just checking. I guessed that migration prompted your post. Not excusing the current state, but it's the way it is at the moment. See also: this bug.

It is quite simple to make the required changes and it only has to be done once, but I agree that it could be better. My solution is to use rpl. Simple and effective, requiring only Python, and the changes can be done either before or after migration. I run it in the /data/pages directory and on the /dats/other/components.xml file.

Alternatively, Komodo Edit is a free, cross-platform editor with the ability to Search & Replace in a directory or directory tree. It can work with local files or via FTP or SFTP. (It isn't necessary to open each file for S&R.)
