There's been a couple of threads that you must have missed. One member even went so far as to say that LUA is only for wimps and idiots who can't secure their systems. Real Men don't eat quiche or use a limited account... Some will agree with you, including me. However, "some" is the right answer. Take a look at threads where someone says they need really light security due to old hardware, under-powered netbooks, etc. They get deluged with lists of security apps. If someone suggests LUA and SRP (after all, it's supposed to be light) the post usually gets ignored or the response is negative, equating LUA with wearing a hair shirt to do penance.
