I wouldn't be so convinced that spammers are inevitably incompetent. Just look at how some of them have been studying tools like SpamAssassin and figuring out how to get around the filter. Given that various popular email list to web gateways read the same research that you did and are using HTML encoding to hide addresses, it is only a question of time before that becomes tempting enough for spammers to add a couple of new regular expressions to their web scrapers and catch either @ or @ in email addresses.

Your fred&barney trick is likely safe for a long, long time. There aren't enough people with & in their email addresses to be worth behaviour modification from spammers. The same won't remain true of HTML encoding @.
