We see no reason to remove it as some people will still need/want that option.
If you want to run your car in low fuel conditions and do hard cornering and accelerations without having to upgrade to a better filter, then we'd recommend sticking with the traditional bucket setup and utilizing our DIY option for the best value.
However if you want to take advantage of the additional capacity and know and accept the limitations of wide open throttle accelerations when the tank is below a 1/16, then it's a good option and value for you. While we don't have official pricing on the custom filters yet, it's looking like those will come in at about $150 and $300 respectively. They are not cheap but if the additional capacity allows you to meet your goals without additional upgrades, that is a win/win. It'll be up to you to choose the option that fits your driving style and supports your power goals.
Frankly, we never intended to offer the standard filter option when we started this endeavor. However, much to our surprise when testing, it was much more functional than we anticipated.
We have a half mile event tomorrow and we'll be taking that car. We'll run the tank down and do some runs. As we said, doing normal 3rd and 4th gear runs down to 1/16 of a tank was no issue but this will give us the opportunity to do longer extended runs.
