Right, so there are four options:

1. Never rename / reorganize SUPPORT.md categories
2. Backport all renames / reorganizations to all supported versions
3. Introduce some sort of “mapping” of options so that the table generator can 
correctly construct rows
4. Tolerate duplicate rows for renamed / reorganized features

I was initially opposed to #2, but I think the idea is growing on me.  It does 
mean SUPPORT.md may end up being reorganized or renamed in point releases, 
however.  It’s a bit hard for me to tell how disruptive that would be.
