That's an interesting workaround. The question I meant to raise was whether a workaround is justified, or whether software developers should just maintain the apps they sell.
It depends. If your app can work within the sandbox and it's a one and done like a game, maybe. The Mac platform changes so slowly you don't have to worry as much about incompatibility with s new OS as you do iOS.
But if you ever want paid upgrades or you are already a well known app -no.
For instance it wouldn't make any sense for MS or Adobe to be in the Mac App Store.
