So your belief is that to divide the attack action that must be specifically allowed in a specific beats general sort of way. Good! Then isn't the rule that a bonus action can be taken when you choose sufficient to establish a specific beats general case for bonus actions being able to divide the attack action attacks as well? If it's not then why isn't it?
No. A bonus action being taken when you want is also a general rule, not a specific one. General does not beat general. A bonus action SPECIFICALLY saying when it can be used would be an example of a specific rule.
