64 bits: is there any reason why more Linux software projects do not use & # 39; .x86_64 & # 39 ;, & # 39; .86 & # 39 ;, & # 39; .64 & # 39; and & # 39; .32 & # 39; instead of deb, rpm, Flatpak or Snapcraft?

& # 39; .x86_64 & # 39 ;, & # 39; .86 & # 39 ;, & # 39; .64 & # 39; and & # 39; .32 & # 39; They seem to be very similar to & # 39; .exe & # 39; in Windows. Although I have used Linux for more than two years, I have only seen a handful of programs that use these files for their Linux versions. One of these programs is Godot (https://godotengine.org/), which runs perfectly in any distribution that runs X11 (I think). Is there any problem with this, besides that these programs do not run on screen servers other than X11? Is there anything I said false? Should more programs use this?
