It depends. If the tree has high vitality then perhaps not so much. Other factors are end weight, exposure, pests, all of which can be mitigated, which also should factor into your risk assessment. The term "hazard assessment" assumes a "hazard", and is needlessly negative; Matheny and Clark agree on this point so it ain't just me sayin it.

Eric, I'm with S Mc on your euc cut--reducing to a long lateral like that leaves a long lever that is open to rot at the base. It may be a textbook reduction cut, but by itself it may be wrong. Better imo to cut to a small lateral further up if there is one, angled away from sun and sky, or at least to shorten the lever arm (and experiment with sealant?) if you must make the bigger more horizontal cut.
