The variations posted as part of V101 is a more complicated issue.
We don't know if the bewildering variations in the macron-like VMS glyph are meaningful differences. Macrons varied quite widely in medieval scripts but they all meant the same thing, so variations in shape didn't matter.
But the VMS is different, and the macron-like shapes vary even more than was normal for medieval scripts.
Are the differences meaningful? I don't know. But if they are, then there might be numerous meanings for Sh.
