Any reason the engine would need to be 64-bit, though? Only Server Core 
currently supports 64-bit only, and not much runs on that. 64-bit processes 
affect default registry and file system paths, and while MSI and isolated EXEs 
(including wusa.exe, since we just invoke that) will work correctly, other 
things with Burn may not - like ARP/bundle registration. Fortunately, and 
against the MSI team's wishes, I stuck the package dependency stuff in a 
reflected/shared key but registry searches would be adversely affected and 
setup devs may not realize it.

The engine might be 64-bit, but I don't think that should affect how the bundle 
works.  Things are different for MSI since the package is inherently 32-bit or 
64-bit.
Naming is hard.  I think Win64 works for Burn, I'd have to think about whether 
there's a better name.

What if we had 64-bit Burn that was affected by –arch switch?
 
Ultimately, I think I agree with you. Thus my point in #3 where I’m wondering 
if there is a better name than “Win64”. Any thoughts on that?

Looks like there's only ApprovedExeForElevation and util:RegistrySearch in 
Burn.  These aren't going to be affected by the -arch switch, so it doesn't 
make sense to me to have "force" or "always" in the name.

1. I don’t understand this comment in the WIP:
 

This attribute will not require the "-arch" switch to function properly.
 
The –arch switch is most definitely required. It’s handled by default in 
MSBuild. It’s very, very important.
 
2. I’m also not thrilled with
'Always32Bit'
  name. I like “always” better than “force” but “32Bit” feels funny. Bob can 
you bail us out here?
 
3. Searches in Burn *may* be different. *Maybe* even in MSI. I don’t remember 
if 32-bit MSIs can do 64-bit searches. Anyone else remember? 
 If searches are different then maybe “Win64” attribute is bad name and we can 
come up with a better name for searching hives (that may default to –arch).

I’d like to propose replacing the Win64 attribute with something more intuitive 
in WiX v4.0.
 
Here is the WIP:

I appreciate feedback.
 
Thanks,
