Whatever the semantics (right or wrong answer) I would want to make sure ATC’s expectations were consistent with my plans. Modern aircraft flight guidance systems cope well with turning on to tracks well outside the 30 degrees normally regarded as limiting and many operators take a pragmatic view and simply do it to save time. When this becomes a habit at a particular airfield then ATC may wrongly assume that’s your intent as well even when you choose to do otherwise. If in a procedural (non radar) environment this could lead to an inadvertent loss of separation. Even if ATC seem perplexed by your explanation of intent, other aircraft listening in may appreciate the heads up!
