The MD5SUM field, and others in the .info file, aren't used in a "straight" build script i.e. running "sh xxxx.SlackBuild" doesn't reference xxxx.info at all. In that scenario, the whole .info file is a "legacy thing" or at least superfluous. However there are various build (and browsing) systems which may use any or all of the fields in a .info file. The fact that sbopkg picked up the differences shows that it looks at the MD5SUM field - if only to be informative. In automated build systems, its arguably a much more important find - you wouldn't want those systems to be blithely building packages from intentionally interfered with, or otherwise corrupted, source tarballs.
