Not so much difficulty, as there being multiple ways around resolving the issue. However we do have to bear in mind that we have this issue showing at present with only 1 person (yourself), so while the issue is valid, and we do have a bug report open for it, we have to bear in mind the majority of our clients on this, and ensure any fixes do not affect other areas. Groups of course affect every area of the suite, and the vast majority of people will not have over 62 groups. It's a very individual and unusual use case
