Of course people develop at university and within employment - they develop both their ‘direct skills / knowledge’ and also their ‘capabilities’, through doing and learning new things and carrying out new tasks.
The question is ‘who is responsible for delivering this development’.
The development that is directly related to the course / employment IS the responsibility of the university or employer - skills of presentation, construction of an argument, research as well as knowledge of new subject domains.
However, development of wider skills - self management of competing requirements, self advocacy, social skills, independent living, skills gained through membership / leadership of societies etc - those are the responsibility of the student / employee. If they are specifically lacking eg for reasons of disability or change in direction, then support, training, adjustment to bring them up to an adequate level may be required if they impair job performance that is otherwise exemplary or to mitigate disadvantage.
As a parent of a disabled student, reasonable adjustments are, ime, to allow them to access the course and graduate. They are not there to enable ‘a typical student experience’, ‘full personal growth’, or even ‘a particularly nice time’. They somewhat reduce the overall impact of disability on academic performance, and no more.
