@rashil2000 Requesting review. (and double-check)
I don't usually do this, but I want this to be fixed sooner. Thank you.

Hey, no worries at all, just ping me when needed.

Since from 21.8 they don't provide a 32bit version, would it make sense to move the bin, shortcuts and env_add_path fields outside of the architecture block?

This will make the manifest look cleaner,
but it looks weird when there are bin\\x64 inside the binary path.

Another way is to move all the items out of architecture -> 64-bit block, but this will make Scoop unable to stop the installation on a 32bit PC.

I personally think we can remove all the 32-bit support, since there are few 32-bit PCs in use.
However, we should keep the pattern before further discussions and decisions (from all the maintainers)

Okay, then I think no further change is needed. Looks good to go!
