The general view from legal experts who were willing to comment is that the issue of potential CSAM material proliferating around the Bitcoin network is one that already exists.
Only one of the seven respondents indicated the upcoming changes in Bitcoin Core v30 could do any practical harm.
As one lawyer pointed out, the largest threat may be more about politicians eventually using the issue as a political attack vector; however, the reality is that attack vector already exists in a variety of forms.
Many years ago I had a family member tell me that Bitcoin had child pornography on it. I said something along the lines of if someone has your email address and sends CSAM to your spam box it doesn't mean that you asked for it, approved of it or even knew about it.
