I did specify that it's a tradeoff. If you are more worried about someone having a cache of exploits on all the popular crypto than you are worried about someone taking the time to break your home crypto, then perhaps you should roll your own.

But understand that the amount of effort required to break home grown crypto in the first place is usually orders of magnitude lower than to break standard crypto in the first place.

By the same token the amount of effort required to break not one but hundreds of thousands even millions of different home grown crypto becomes orders of magnitude higher.

No, you'd just develop automated processes for identifying the most common mistakes. Home-growers would still likely all be using the same building blocks. And making the same classes of mistakes.

The dragnet probably wouldn't be nearly as effective, but the NSA would be far more likely to be able to compromise all priority targets.
