I second everything you said! But you worded it clearer 
just to be able to customise the items that are not able to be customised anymore is enough of an issue. It's not about being spoilt or irked. Have you ever tried to help an 80 year old use it? I do daily. Up until recently we had it setup so he could do the needed things. Example, keeps forgetting where contacts are, looks for the yellow button we placed on the home screen. Only now, it's red. Not a problem for able bodied users or younger non dementia users but that one "small" change is causing him fear and chaos. I have more examples from university students and disabled students, dyslexics and lots of other conditions, not just my 80 year old Dad, who I want to explain can't remember yesterday but is still fitting locks part time at his age perfectly. These things are all important and the whole point of the upgrades and adding a.i is meant to be helpful, for me as an IT support tech it's annoying and I am hitting the wrong buttons in a hurry due to muscle memory and having a Samsung since the Note 2. I'm now forced to look at older models with the previous operating system so my Dad can hopefully use his phone again, it's also upsetting him and he's almost distraught. Imagine being old enough to fix locks but not make a phone call! Sorry for banging on!! 😎
