I think you should expect to be able to do more than the demonstrated, especially since a 172 is only at 15kts, at least out here in the west. Our field elevations around here are rarely below 5000 feet and winds rarely below 12-15kts steady. My last cross country I landed with a 90 degree 16kt gusting 22. You get used to it...although it took me awhile to get comfortable with crosswinds , I had issues with giving thatmuch rudder in the flare to keep centered, just felt WRONG.
I guess the max would theoretically be the wingtip touching the ground, or the rudder not having enough authority to align it for the bank angle killing the drift. Assuming you wanted no sideloads on the gear of course.

Not true in every airplane. In a low wing, you'll likely hit the aileron limit first due to ground clearance issues. Prime example..KC135...18 inches under the inboard engines.

Legally limiting yourself

A similar example involves gross weight. If I remember correctly from the Douglas ground school 20 years ago, Delta bought an MD-88 version which had been certified at about 160k MTOW, but had our certificate state just under 150k (for lower landing fees), so the lower number became totally binding on us. Delta (or, if the airplanes are sold, the new owner) could re-certify up to the higher MTOW (for a fee, of course), and then that would become the limitation.
