I didn't re-read it, but I probably jumped to conclusions, and you are right.

I see the majority of (good) software as the controlling factor,
and beeing mathematically oriented I hardly react if they accept
East longitudes in the interval 0...360 or -180...+180

But I do prefer the East +tive, because it agrees with the direction of RA,
and UTC offsets, and it creates a right-handed coordinate system.
