Primarily, because during development of the toolset it is basically impossible 
to follow the Component Rules required by all other forms of upgrades.  Major 
upgrades allow us to change the structure of the product pretty freely.

Secondarily, all the other upgrade formats are basically a pain. The WiX 
toolset install isn't that big so a major upgrade works fine.

Can you please give me some insight as to why do you use major upgrades for
every release?


Thanks,

The goal was to provide a UI extension to make it easier to use
WixUI_Advanced, with a line or two of XML instead of a dozen properties
and variables. That hasn't happened yet.

APPLICATIONFOLDER is used in WixUI_Advanced to support per-user installs
(which the WiX installer doesn't support). WixUI_Advanced sets
APPLICATIONFOLDER.

They're used for the MSBuild tasks and targets.
