Patrick,
In an attempt to get an up-to-date interpretation on this point, I just
emailed the Certification Lab that I work with to get their
interpretation of this rule.
I'll post their answer as soon as I receive it in the next few days.

Mike,
You are right, but you, as an operator, cannot make the choice or decide
on your own what antenna toi uses, even if it has similar propagation
patterns and a lower dBi. The FCC still requires the burden to be on the
manufacturers to add antennas, it just does not make us go through the
wringer now for every change. I do not know how many times I have to
explain this on the various lists, but that is the fact. The order
clearly says this AND I was there at the FCC right after the order and
they explained that clearly, much to the chagrin of Marlon and others
present. Here is the part in the order that clearly discusses the fact
that it is still the manufacturer that holds the burden: "The
manufacturer must supply a list of other acceptable antennas in the
literature delivered to the customer."

Subject: [WISPA] Flexible antenna certification
Many times I've been asked to prove a regulation I swore happened. It
was the one stating that once a radio manufacturer certifies a radio
with an antenna of x gain, antennas with lower gain, but a similiar
pattern and gain characteristics can be used without certification.
On various lists I have been basically laughed at. Well, I found a
reference to it today, so I tracked it down.
Here is the text of the R&O in question:
8. In order to support more flexible antenna requirements for
unlicensed devices, the Commission proposed to allow that devices be
authorized for use with multiple antennas. Although the Commission
proposed to modify Sec. 15.203 to implement the modifications, it
believes that the changes are better suited for Sec. 15.204.
Accordingly, the Commission modifies Sec. 15.204 to permit intentional
radiators to be authorized with multiple antennas of similar in and
out-of-band gain and radiation pattern. Compliance testing for the
intentional radiator must be performed using the highest gain antenna
that will be used with the device. The manufacturer must supply a list
of other acceptable antennas in the literature delivered to the
customer.
