This is a big subject. There are numerous things I have hesitated about over the years, for various reasons, and in most cases have since changed my mind in one way or another. Something I have "looked at" as a teacher is whether my hesitation is truly based on what is best for my student(s), or whether it's mainly a personal hesitation and bias that is based on some personal experience in my own learning (and one which I don't necessarily immediately understand how to navigate around and work with). Obviously it's wise to learn from our own experience, but it's equally wise to pay attention to what the student actually needs.
In most cases, I try to understand what principles are involved which surround the specific aspects of learning that I feel are important, and my teaching is becoming more based on principles than on a single, very specific path that every single person must walk down in precisely the same way. There is a lot to that, so I will just leave that concept there as is, but that is to say that there are actually some very important principles involved with a student learning by rote/ear, and because of that I think it's ultimately very smart to include some form of rote/ear teaching in an overall curriculum.
I do understand what you are talking about though, and I myself am not willing (at this point) to teach only/mainly by rote/ear, but I have only just recently started to understand why that truly is, and what I feel is important about it. I tend to believe that a student who thinks they don't want to read and would prefer to learn only by rote/ear, feels that way because they associate certain unlikable things with reading ... or do not know how to associate what they like about music with it. I can actually empathize with this, not because it was my exact experience necessarily, but I can understand why/how a student could get this impression. So, if I am going to truly address that as a teacher, on behalf of the student, I feel it is my job to help them bridge the gap between what they like about music and believe is not possible when it comes to reading. That is not necessarily an easy task!
So, to sum up:
1. Is your thought actually about the student or you?
2. There are important aspects of learning by rote/ear.
3. It is a teacher's job to help a student bridge the gaps between what they think they like or what comes easily for them. and what they think they don't like/is difficult for them (and that can definitely make the job much more challenging).
