Even if you did this, your mobile users will still be mad, because they cannot hover.
The question isn't if you or your clients are happy with them. The question is if your users are happy with them, and if they generate better business results (conversion, clickthrough, whatever is relevant to you) than the simpler, less Javascripty, less timing-based, less gotcha-with-the-mouse-hover implementation.
Though some have a habit of stubbornly ignoring any professional advice against a feature they have an emotional attachment to, raw data can sometimes snap them out of it.
I am a mobile user, and I can hover. In Chrome on Android, when I tap on an element that doesn’t have an action of its own, that element always acts like the cursor is hovered there. I was able to use this to pause the carousel on http://shouldiuseacarousel.com/. And on other sites, if I tap and hold on a link, then close the dialog that pops up, the link still acts like it is hovered over.

I sincerely hope you A/B tested this.
