Right, I didn't even consider it like that. But yeah, theoretically we
could drop the wic variant if you only use fsimage in your wks file.

But I think they sort of complement each other though. Since the rootfs
plugin does exist in wic, it makes sense that it would also support
--exclude-path. If you have a partition setup like this:

part1: Everything except /usr
part2: Everything inside /usr except /usr/share
part3: /usr/share

This would not be possible without --exclude-path support in wic, since
part2 would have to be constructed using the wic rootfs plugin, but
would need to exclude /usr/share.

In any case, I will definitely look at implementing the do_image_ext4
variant as well. I'll post more info about that when I have it.
