I'm not sure what you mean by stripped threads. Metal is stronger than plastic, there's nothing the PLA blob can do to cause physical damage to your hot end besides damaging cables. And I don't know what threads would be exposed to even be damaged.
I mean if you're wanting to buy a new hotend by all means get one, but don't do so thinking you have to because of this. I almost wanna guarantee everything still works as long as your cables are intact.
True but, with pressure, water can cut metal. I'll be heat softening it with my PCB toaster oven to see if I can recover it. If it's just a leak, and no electrical damage, as you mention, it's probably ok.
Probably, I'll still get a new hotend, even if there's no breakage because I think that the PTFE feed tube is a bit of a weak link.
