The spar is now even stronger!
aah ahaha ahahah haaah haaaaa!!!!
Caught ya!
It's not a loose footed main, there's a rope bolt!
The force is from the sail distributed along the length of the boom. The
boom keeps the sail from pulling up, that's right!, pulling up!! The forces
of the mainsheet in the downward direction are minimal and occur at a point,
not along the boom. The force of the vang, at best only 1/2 downward are on
the front portion of the boom.
Simon has done well.

Simon's spar is even stronger because of the bend!
That's right, folks! The neutral axis for tension and compression due to
bending has been moved off center, when stressed, more of the boom is in
compression rather than tension. The mid center joint means nothing with
such a clever and knowledgeable repair!
Excuse me but I believe you are wrong because of the direction the boom is
bent. For it to be "stronger" it would have to be arched up in the middle
away
from the pull of the mainsheet and vang.
