TESB has a very peculiar structure: for example, every scene begins with our heroes making progress, but always ends with the omen of a new danger. Because of this, I think General Veers's death was cut mostly because it would've made the Rebels look victorious, breaking the structure.

Very peculiar structure in some places I could not agree with more...

It all depends on which order the scenes were originally shot in and how they were edited afterwards.

But you are right about always presenting a new danger but also suicide crashing kamikaze style is not victorious or a battle won, it's a very desperate means and no doubt would have been portrayed as "Hobbie" Sacrificed himself to save others.

In ROTJ the original idea was portrayed as a victorious moment in a battle though. The pilot sacrificed himself to destroy the Super Star Destroyer which in turn saves lives but it was also not made to feel totally deliberate as he was spinning out of control. Hobbie Slammed the AT-AT with intent knowing he was going to die.

This is the sort of mood you could expect afterwards.

There is something else I also want to add in about the actual End result that we saw the shield generator being destroyed rather than general veers death. Although the shield generator destruction is a check mate move the base was still vulnerable to attack because every time they wanted to shoot the ion canon and let the transports escape they had to open the shields so general veers death was more of an important plot point than the shield generator destruction. But i think both the plot points are valid.
