Is there any in universe reason for the Trade federation having their reactor run through the hanger bay?

In TPM Anakin simply flies his N-1 Starfighter in hanger and accidentally sends a stray torpedo into the ship reactor core. I know the real reason, but what's the in universe reason.

We know the early Trade Federation ships were converted cargo ships, could it be that there was some benefit to having your reactor in the inner hanger?
