I think it's more likely to be a hand-crafted font, inspired by the general layout of stencil letters but no more than that.
On top of that there are a billion stencil fonts! There are thousands of them that narrow near the stencil dropouts. Seems like the author is making wild speculation.
“As one of the creative leads on the id software brand team at Pyro in Texas, I worked on the logo, font, packaging and advertising, as well as the global E3 launches, for Quake, Quake 2, 3 and 4, some of the most iconic video game launches in the history of gaming.” http://www.sashashor.com/new-page
IANAL but I believe you can trace even a commercial font and use it. Making a bitmap font from print and using it in a game should be fine.
Must've blotted it out to preserve the affection I had for the first 3.
One cool thing the game did was they used the DOOM 3 "interactive panels" tech to make not only English-language human-manufactured "touchscreens", but also Strogg-language alien-manufactured "touchscreens", that you had to interact with to open doors and so forth. After becoming "stroggified", the glyphs on the Strogg touchscreens shift and you can now read them in English.
I went back and replayed it a few years ago and it's really pretty generic as far as shooters of that era go, but I thought Raven did a decent job given what they had to work with.
Instead of looking for which vector font that have been rasterised at this resolution, I would sooner look for the font in bitmap font collections like this:

I wouldn't be surprised though if the font was created 'from scratch'
Two clicks in.
Some stones are best left unturned...

“The company received extensive criticism for its strategy of cheaply offering digitisations of pre-existing typefaces that it had not designed. While technically not illegal, font designer John Hudson would describe its selling of large numbers of typefaces on CD at discount prices as "one of the worst instances of piracy in the history of type".
Like a lot of font foundries, monotype ended up buying that one.
