Is forcing older IE into quirks mode bad?

Question

I built a web app using some technologies that do not work well for IE 8/9. The app functions well in Chrome and Firefox and mostly okay in Standard IE 10 but breaks down in IE 8/9 standard. However, if I switch over to quirks mode for IE 8/9 in the developer console, it works perfectly for some reason. Is there a danger to trying to force quirks mode for older IE?

Well I would say that it's definitely not optimal and you should be trying to fix the errors that prevents you to run in standard mode, however if you are unable to do it and it's the only way to go, I do not see how a working application running in quirks mode could be worse than a failing application in standard mode.
