override files in winecfg: Why makes it sense to set files to builtin?

[Opako]

This is my winecfg "override configuration" after installing a program in wine:

What I do not understand:
1) There are entries that are set to "builtin". For example "ctfmon.exe". I thought, that using the builtin version is anyhow the default. So why is it set to builtin?

2) *docbox.api is "ausgeschaltet" -> meaning "turned off".
What can be the reason for "turning off" any file?

Would appreciate some clarification. Thank you.

1. I'm not 100% on this but 'builtin' meaning 'builtin only, never native' may have some use. Or it may just be down to having a consistent interface.

2. 'disabled' in english, I believe. Which prevents the dll or exe from ever loading which is useful in certain circumstances. Possibly to prevent running some optional component that has issues, or prevent some program from using a certain api that causes issues, whether bugs or undesired behavior. etc.
