"Pedantic" in this case means, "If it didn't show up in the magazine, it isn't part of the font." That means there are no lower-case letters and a few other symbols, but there are alternate letterforms as the font changed over the years. Default kerning is set to be as close to "type a word and get a perfectly set header" as possible, keeping in mind that was done by hand back in the day, and this is a digital recreation. Typing "OMNI" in "upper case" should emit a perfectly set masthead. Includes various symbols used throughout an issue, like the "Anti-matter" symbol and end-of-article marker.
Others have made similar typefaces, and I talk about how mine differs on the github README. At the end of the day, this is not "a font inspired by OMNI." It aims to BE the OMNI font.
