If not using statutory exclusions, the plan must meet the requirements of §1.401(m)-3(d)(4). I agree with this statement made by the OP:
"if you are eligible to defer you are eligible for the safe harbor match unless you are utilizing the statutory exclusions."
I guess I don't understand your statement. If you want the "plan" to be ACP safe harbor, then it must satisfy all of 1.401(m)-3, including 1.401(m)-3(d)(4).
The issue is: what is the "plan"? If you are applying 410(b) separately to those who could be excluded, then you have two separate "plans" for testing. One "plan" covers the employees who have satisfied the lower minimum age and service conditions in the plan, but have not satisfied the maximum statutory age and service conditions. The other "plan" covers employees who have satisfied the maximum statutory age and service conditions. See 1.410(b)-7(c)(3).
Suppose you have a plan that provides for immediate eligibility for deferrals and requires 6 months of service with semi-annual entry to receive employer contributions, including the SH match. You choose to treat it as two separate plans under 410(b) because otherwise, as you point out, it won’t be SH.
The first “plan” to test is the eligible employees who satisfy age 21, one year of service and semi-annual entry. All eligible employees in this "plan" are eligible for the SH match. So, assuming no other problems, this “plan” is SH.
The other “plan” is the eligible employees have not satisfied age 21, one year of service and semi-annual entry. This is all eligible employees who are not in the first “plan”. This includes some who are only eligible to defer and some who are also eligible for the SH match. This “plan” does not satisfy 1.401(m)-3, so it is NOT SH. Also see 1.401(m)-3)(j)(3). But, do you really care? In most cases, this “plan” will not include any HCE’s, so it will pass ACP. If an owner’s family member is in this plan, then they may get a refund their first year. In a 403(b), the sponsor is a non-profit, which doesn’t typically have owners.
