Debate: Should we prune oaks in summer or wait for dormant season?

I keep seeing guys on job sites cutting live oak branches in July, and they swear it's fine if the wound sealant goes on right away. But my arborist training said oak wilt risk spikes hard between April and October, especially in areas like central Texas where it's rampant. I had a client lose three big red oaks last year because a crew pruned in August and didn't clean their saws between trees. On the other hand, some research says summer pruning can actually reduce regrowth stress compared to winter cuts. What's your take, do the benefits of a quick summer trim outweigh the disease risk for you?

...and that's the thing that gets me every time, because people who say the wound sealant fixes everything are just ignoring the beetles that carry the fungus in the first place. Like, you can put tar on a cut all you want, but if a sap beetle shows up within 48 hours, that tree is still getting infected, and I've seen it happen too many times. But I gotta ask you though, in your experience, do you think the whole "summer pruning reduces regrowth" argument even holds up for oaks specifically, or is that more for like maples and stuff where the growth habit is totally different?

Oh wow @abby_singh, do oaks actually bounce back better from summer cuts or does that just slow them down more?
