Would be better to introduce genetic incompatibilities so that GMOs were infertile with non-GMOs.
I guess if that was your goal they would probably have to insert a novel gene that wouldn't be present in say, the over 10,000 different varieties of conventionally bred tomatoes and then engineer the plant to produce sterile seeds, but that seems like a much more concerning trait to let out into the wild than beans expressing umami flavor. Terminator seed technology has been around for a while but as far as I know there have been no commercial applications because it worries a lot of different groups.
Adequate buffer zones won't be 100% implemented, though. Nobody's going to make them do that worldwide.

You can make plants unable to interbreed efficiently by inducing and exploiting polyploidy.
