The weird step for me is the expansion of regulatory authority from published memos, to all written communication like texts and chats. I get it and don't really object to the end result, but it seems like the law should be updated to match what society desires to be regulated, rather than just relying on a generous interpretation by regulators.

I wonder if handwritten notes, post-its, or marks on whiteboards are also subject to regulatory authority.

Yes they are, if you haven't taken care of keeping them out of sight of unauthorised other persons.

This absolutely happens. Usually, however, the regulators are interpreting the law in a way that the legislators agree with. In those cases, there is no need for new legislation.

The law does not need extending. It is that for bank traders ALL communications must be kept.

One, not every securities professional trades at a bank. Two, this is not true for any of them. Broadly speaking, work-related written communications must be logged. But there is nuance and exception to that.
