In the purest theoretical sense yes, in practice no. So that you don't have to recert everytime, you
1) test and exercise your product to extremes so that you can say with high certainty that: no matter what the customer loads, it won't breach the rules.
2) As pjc50 mentioned: Lock down the parts which the user could potentially cause the most damage with. i.e lock down that radio firmware (why is why none of it is open source).
If you do (1) and (2) and a few other things, you buy down your risk sufficiently that you can confidently demonstrate that re-certs are not needed.
The Author of the parent article IMO is doing the exact opposite.
There are also half-way houses: Just doing "pre-compliance testing". So not a formal cert, your just doing a quick test in an anaechoic chamber or even on a table top scanner. Of course this only applies to things you can self-certify. Some things, like radios (WiFi, Bluetooth etc.), you cannot self-certify. That's why almost everyone buys the radio as a module (To buy down their risk). By consequence: That's why those radio module manufacturers have the firmware locked down hard and engineer and cert the radios to have big margins.
There are a lot of rules yes, but there is actually a lot of flexibility and common sense in the system too (but it is still imperfect, absolutely). But that flexibility does not allow for horsing around. If you can demonstrate to Friendly Spectrum Agency all this due diligence, you are going to have a MUCH better time.
