Very interesting way to look at this.

People are so often worried about spreading antibiotic resistance
genes, and assuming that lack of pressure means the actual lab-strain
E.coli/organism are negligible to the environment (other than by
donating transgenic/advantageous DNA for possible uptake) since they
will soon start to succumb to real-world conditions (as opposed to the
comfort of a lab tech feeding/defending and caring for them).

I've heard of people drinking K-12 E.coli, with no apparent effect,
but would an E.coli with bacteriocin system completely replace the gut
E.coli community?
