Sort of. I would say indirectly at least.
A lot of campus policies (most notably financial aid) use “academic progress” as an eligibility qualifier. As a transfer, your “academic progress” will be based on your admitted major until you officially declare a major so not taking any courses toward your admitted major will jeopardize your eligibility for most aid and can affect your registration priority.
Berkeley also takes the [L&S unit ceiling](https://ls.berkeley.edu/advising/planning/enrolling/unit-ceiling) very seriously so exceeding the unit ceiling can be a costly mistake should you need to spend a fifth and/or sixth semester at Cal.
