I find it very rare that TSOs are paying that close attention anyway. I used to regularly travel with toiletry products in bottles around 4 or 4.5 oz. because one product I used didn't come in anything smaller, and they never blinked an eye as long as they were in the quart bag. Even before I had PreCheck I eventually stopped taking out my 3-1-1 bag unless asked, which was maybe once every 15 flights.
