You can mail it out to modders for modification or just buy a front loader with composite out and snip the CEC chip ground pin to make the front loader reliable. Lots of options. The best thing about the top loader is the controller for sure. I was turned off by the NES Classic mostly because I find the rectangle controller, while classic, uncomfortable. I personally use a front loader with a collection of my old games, and a 100-in-1 cart for the rare games I'm missing...
But if they make an SNES classic, zmog.
Unfortunately, disabling the CIC only marginally improves reliability. The same reliability issues that affect the CIC connection affect the rest of the connections in the front loader. In other words, when it flashed a blank or corrupted screen, the only difference will be that it doesn't flash/reset. It will remain blank or corrupted. With 72 pins that could go wrong, those four really don't count for all that much.
Even with a normal brand new aftermarket connector, reliability will never come close to the top loader. What we need for that is a product called Blinking Light Win. It's a different kind of replacement connector that has a built-in CIC clone (eliminates the CIC connection from the cartridge) and loads without pushing down, like a sideways top loader. It actually includes a new tray that prevents you from pushing down.
The only drawback is that it feels super tight, like it has a death-grip on your cartridges. It was designed to be comparable to the top loader's tightness but there isn't enough room to grab the cartridge and it's a real pain to remove them with the tips of your fingers. I noticed that it had all 72 pins including the auxiliary and CIC pins that even the top loader leaves out (if you look inside you see that it's missing many pins in the middle). I removed them to reduce the friction and then removed even more unused pins, like CPU CLK. All in all, it was a 22%+ reduction in pins. The death grip is significantly reduced. Though it may still feel WAY too tight, feeling it side-by-side with an unmodified Blinking Light Win reveals that it's a night-and-day difference.
