Remote start only plan

I hadn't looked at OnStar plans for awhile, and now that I'm interested in getting the remote start through the app working again. I'm completely unwilling to pay $15 a month for a bunch of useless junk from OnStar when the only function I want/need is remote start through the app. What's it take to get the plans updated to allow for a cheaper access to this function without all the fluff that's included on all the existing plan structures? If OnStar's long term plan is to eliminate the low cost access to this feature, it would be nice to know because I'll pursue other aftermarket options that fill this function at a reasonable price. The aftermarket options prove that this functionality shouldn't be cost more than $30/yr.
