Is heater core failure inevitable? 900 1994

My heater core is currently fine, and yet this is hanging over me. Like waiting for the other foot to fall….

The mechanic I go to has already told me that he will not do a heater core replacement.

From what I have heard, I am not sure that I would want to do it, either.

My question is this: will these necessarily fail? Other than regular coolant changes, which I have done for 21 years, is there anything else I can do to prolong the life of my heater core?

Should I, for instance avoid power flashes of the system, which I understand can precipitate a leak?

Any high mileage cars that still have their original heater cores?

And is this job is horrible as I have read in the FAQ and elsewhere?

Fingers crossed. Thanks.
