Ir blaster and fm radio and empty sd card slot use no power when not in use so do no harm. Removable battery is more practical since batteries lose capacity over time. Both of us could be pleased. Saying their presence hurts the phone sounds silly unless you can cite how.
I've made the argument in many places over the years, but it's all about opportunity cost. The inclusion of these four features, all of which I consider to be either useless, degrading the user experience or just superfluous comes at the expense of other priorities, either directly or merely as a result of the cost of adding the feature (money, time, resources). Three of them take up physical space, all of them entail extra code for support, three of them come with design compromises, etc, etc.
There are some features that I think ought to be included in phones, some that ought not and some that it doesn't really matter. In the foremost, I'd say a camera, NFC, display, battery of sufficient size, etc ought to be included in devices. Things that ought not to be included might include, a removable battery, sd card slot, slot to hold an extra house key, mouse taming ultra high frequency sound emitter, analog display brightness knob, etc, etc. For the doesn't really matter category, we could include on screen or off screen buttons, a headphone jack, etc.
Three of your wishlist items, to me,so in my opinion, shouldn't be included at all on any device and the other one doesn't matter.
