Arbitrarily complex expressions are possible, which is problematic with UI representations. With the two-level structure, updates and notifications become either more complex, or less efficient.
Ah, now I see that I didn't understand your proposal; so, you mean to
have only one rule per account, consisting of a list of
Account_Conditions and Account_Condition_Rules, right?
If so, then, you will not be able to express a condition like this:
connect the account if (A and B) or (C and D), but since I cannot think
of a single case where we might need similar conditions, I guess we can
forget about it.
And then, indeed, your proposed scheme is definitely simpler.

If the condition namespaces are the same, yes; but if some condition
appears in the presets and not in the account, it should be taken into
