Do you prune off your fire blight?

I was pruning one of my pears today and took off a big branch with scorched looking bark.
Then I saw a few more that I need to remove tomorrow when I get the ladder out.
But then I realized that the bark of the main trunk looks infected, but the tree seems to be basically doing OK.
So I started to wonder, is it better to prune it off, or will the tree learn to live with it? I'm not going to take it down while I'm still getting pears.
I know pruning it off is recommended, but does anyone have experience with letting it be?
We sometimes get a wet spring that helps the fireblight spread, but we also get dry ones, where the trees don't do so badly.
What's your experience?

We had a large Bartlett pear on our property when we moved here and it would always get a few fireblight strikes on it, sometimes a smaller limb, and sometimes a good sized branch would get it. I would cut off the bigger ones that I could reach, but there were a few very large branches up higher that I couldn't easily reach so I left them, and I usually left all of the smaller ones too because there were a good number of them.

The tree was generally healthy despite multiple pretty large fireblight strikes, and the main trunk never seemed to become infected, just the branches, so it would probably be fine for you to leave it. I think a lot of it has to do with the variety too, where some varieties may be almost completely immune and some extremely susceptible.

I've also seen how some varieties even though they may be susceptible seem to stop it from spreading to larger branches, where on others it spreads more easily and can end up spreading to the rest of the tree and eventually kill it.

The biggest issue for me with the fireblight was that it seemed to affect the flowers the most, and killed most of them, and as a result it affected the tree's fruit production a whole lot. I bet it may have done better if I cut out all of the infected limbs to reduce the spread.

This tree never actually died, but I recently cut it way back and am converting it to a multi variety pear tree with a lot of different varieties growing on the tree.

To try to avoid fireblight altogether as much as possible, I've mainly switched now to varieties that are very or moderately resistant to fireblight due to its severity in my area. I am still growing other more susceptible varieties, but just for breeding purposes due to an excellent taste or other valuable trait they have.

Hope you get some pears soon!
