    That's not stress. That's a growth striation. The bark can't keep up with growth, usually after lots of moisture and splits. Normal, not anything to worry about and happens on a lot of trees.

    Those limb attachments are hard to discern but it's such a bad lopping I wouldn't trust them. Did an arborist lop that down or did you?

    Yes, it's ugly. Damage was done long before we arrived on the scene. I am a bit worried the big stump may cause rot into the center of the trunk.

    A lot of Eucs are hollow through rot, they don't mind.

    I saw a van crushed by some epicormic growth at a storm damaged site on the original leader. The reaction wood hadn't enveloped the snapped branch and basically the new branch peeled away. A big branch held up by a quarter of the wood it should have had.

    for me any gum tree that has been severely lopped or cut back is more dangerous than in its original state and for me it would need to be removed. those growth branches that come after lopping are more prone to falling off.

    Isn't allelopathy when a living plant puts out certain chemicals in the soil that discourages some other plants from growing there? That's different than chopping up that tree and mulching it and composting or using it on the garden as mulch (which is where there can be a problem with the volatile oils).

    I think there are other conversations about how gums can be useful (either here or at permies.com), but I can't remember if it was living trees or as mulch. If it were me I would experiment with the different parts of the tree when you cut it down (chipping, mulching, hugelkulture etc), and see what happens. I wouldn't use it on the important bits of the garden until I knew what I was doing though.
