Remove the ISO limitation on the powershot cameras with the new CMOS sensor

Question

I like to take profesional looking photos and have full control of my camera, I like to use a powerhsot as it's compact, light and not too pricey incase something bad happens to it as I take it into some pretty risky sitations.
I have a PowerShot sx700 and have had no problems with this camera except that I encountered an ISO limitation to ISO100 when I set the shutter speed  to times longer than 1sec. I like to take long exposure photos at night of times up to 15 or 30 seconds and somtimes they require a very high ISO. There is no CHDK firmware avaliable for this camera yet, otherwise I'de be more then happy to void my warranty to install that firmware to get a fully functional camera.
Who here agrees that canon should update its firmaware to remove this limitation in manual mode? and if it's not too much to ask; extened maximum shutter speed time to 30 seconds.

I'll say with near certainty that Canon will not release a firmware update to address this.  Aside from their top-of-the-line dSLR like the 1dX and 5d3, they rarely release firmware to add features, only fix programming errors.  I don't pay too much attention to point and shoot updates, but even on the Rebel series dSLR they rarely fix anything because they simply release a new version every year and expect people to just upgrade if they're unhappy with their current model.
They added some new features and enhancements to the 7D a couple of years ago. They bragged about it a bit more than the changes justified, but they did add one really useful feature: the ability to control the names given to the image files. So when you do a photo shoot with two or more cameras, it's easier to tell which camera took which image when you start editing.
