My concern would be the side wall failing around the repair If under heavy stress like an emergency stop or an evasive manoeuvre. And each to their own of course.
The amount you know about these things likely informs your judgement, and I’m ignorant enough, while also of the opinion that reliable tyres are one of the cars main safety features, that I err on the side of caution. That’s not to say I haven’t made similar decisions in the past either!
Tyres don’t catastrophically fail. You’d notice it going down long before it caused you an issue. I’ve sat behind a van on the motorway bobbing along on a tyre so flat he was getting sparks off the rim every now and then.
