With all due respect, that's going to bite you in the rear the first time a patch comes along that requires a new "homecoming.exe". You're going to have somewhere between hundreds and thousands of people posting here about not being able to get into the game. And most of them won't read the announcements to see that they're supposed to change manifests for the patch. It doesn't even take a major feature upgrade to require the main exe to patch - it could be a client crash was discovered, and the patch has to be rolled out quickly.
Being in software, I can tell you that any time there is something that the end user 'should be able to figure out', they absolutely won't, and it will become a huge headache for you at the very moment you don't need one. Like this thread!
We know; the download link was removed intentionally shortly after to suggest to people that perhaps they shouldn't use that manifest. (Why we didn't just pull down that manifest altogether, as I was led to believe initially, is unknown to me, but this is what we're doing.)
I would also note that most people did not see that manifest and have no idea it exists, and those that do, apparently, are aware that it's not the main manifest and that they should switch to the correct one (which is loaded into Island Rum by default as it is in Tequila, yes?).
