Why do type designers not create dedicated fonts for film subtitles?

There are fonts designed for film sub titles out there and one I immediately can think of is Bluescreens .

This face is certainly not intended for subtitles. It appears to be meant for listing the people who worked on a film at the bottom of posters and such. It looks suspiciously like there was a requirement somewhere for letter height and they made it as narrow as possible to be able to squeeze as much as possible into a line.

Yeah, I Initially misunderstood what was meant  by the phrase 'sub-titles'

Why do you think any number of available fonts would not suit this purpose? I think whatever software is available to do this on the fly probably does not have good enough resolution or good enough rendering.

Not my experience. The modern subtitling tools, which include Adobe Premiere and DaVinci Resolve, can render text just fine. I do think some of the available fonts would suit, but I'm not sure which ones – after all, I'm a subtitler, not a type designer, so I wouldn't know what to look for. It'd be easier to find and pick a dedicated type.
