I feel it may be able to discuss in other places but let me say one comment.

If more GUCs were found which cannot be set during the bootstrap mode, how about
introducing a new flag like GUC_DEFAULT_WHILE_BOOTSTRAPPING for GUC variables?
If the flag is set all setting can be ignored when
IsBootstrapProcessingMode() = true.
