Normally I would not like to edit the skin provided by Forrest as I
have done, for the maintenance reason you cited.  However, the
document I read on creating a new skin seemed to strongly discourage
users from creating their own skin unless they could not do what they
wanted by modifying an existing skin.

In this case, I would take that to be an encouragement to copy a skin to your project and modify the copy, rather than start from scratch. It's a great way to learn about skins, which could further lead to adventures with custom skins from scratch or heavily modified standard skins.
