If you look at https://api.github.com/repos/llvm/llvm-project/releases, anyone can see the download numbers for each asset. For the latest release, the numbers are as follows:
- `LLVM-17.0.6-win32.exe`, 1657 downloads
- `LLVM-17.0.6-win64.exe"`, 63491 downloads

So clearly much less downloads, but still a somewhat nonzero number. Whether it makes sense and is relevant to keep doing, I don't know though. (For my own releases of llvm-mingw, I won't discontinue x86 builds for a long time.)
