Chips that are "V" shaped into the glass cause stress concentrations, but those that are ""U" shaped into the glass are not a problem. (Of course getting cut on sharp edges is a problem for you.) When I removed the rims on a couple of small tanks I had, I also had small chips pulled off by the adhesive. I used a silicon carbide sharpening stone to get rid of the sharp corners left.
When you use euro bracing even large tanks can safely have the rim removed. If I remember correctly, the braces have to be cemented to the inside of the tank, not across the top of the tank, which was a problem I never did figure out how to solve. (Silicone joints are far stronger in tension than in shear, which is why the tank bottom needs to be inside the sides and ends, not outside.)
