Yes, and the BSD vis is part of MacOS which quite a few people use.

There was a homebrew package for 0.2 but it was deleted. Not sure if was replaced with a different name.

How about vi9 for a name? Or Vine. Pretty easy to type since the 9 is just above the i on the keyboard. (qwerty)

If being easy to type is the criteria, I would suggest vij, vio, vil, vid or via, since that's where your fingers are likely to be after typing vi if you are touch typing.
