Well, that's because Trackers and modern DAW/Sequencers are different types of music production software.
However, for the 'type' of music production software that each actually is, that is exactly what the note editor of trackers and the piano rolls of DAW sequencers are: 'equivalents' for (and within) each separate music production environment.
The fact that you may personally prefer, or be able to get more done in one type of environment than the other, is completely besides the point and entirely different matter altogether.
You seem to have mistakenly equated the term 'equivalent' with 'identical' and somehow took offence at that, since you can do more within your preferred tracker environment. When that was never the point I was making or had stated.
That being said, 'most' (note: not 'all') of what can be achieved within Trackers note editor views can 'equivalently' be achieved within DAW piano rolls, which is what makes them 'equivalent' to each software's environment (tracker vs MIDI).
