The acoustic double bass can make slap sounds and it would have been happening in Jazz as well. Jazz players use it all the time all be in a much more interesting way.
What could make it boring if over used anywhere is when it is played in a not so interesting manner with poor time. How about use in an amazingly interesting way with great time. Then it could seen as invaluable. False notes of this type can be edited out completely.
Recording it has to be taken into consideration. Placing a mic pointing at the f hole will give you a good sound and augment that with the DI sound. That mic may have to be secured with some form of bracket attached to the instrument itself. Which f hole also depends a little too. One is bassier than the other for obvious reasons so you can choose to mic the preferred f hole. You can mic the f hole from a separate mic on a stand as long as the bass player is relatively still. The string being pulled out and let slap back onto the fret board sound is not so out of control at that position. PA guys can use the DI sound live for volume and a little of the mic sound for realism. The Jazz guys can use it for making themselves a little louder because some modern Jazz is getting pretty loud at times. The Jazz acoustic players need all the help they can get.
Getting a decent mic inside it too could be an alternative to the pickup sound. I wish more double bass players would go to the trouble of doing this. The sound is quite loud in there with minimal spill from the outside world too. I once recorded a (very soft and quiet) Vietnamese zither from inside it as well as outside of course. I was amazed how good it sounded inside and how little spill there was from quite a loud band.
I would be very surprised if that performance and recording reached 130 dB as well. That is seriously loud and a band would have to tbe playing as loud as it could through a pretty big PA in order to reach those sort of levels. I don't see that in the picture. Sounds like there is some form of distortion on that recording as well. Not sure what that is but it could have been recorded cleaner perhaps. Mechanical faults can create very distorted sounds. Like a screw loose in a FOH PA full range speaker or something rattling in a pickup situation.
Eventually a VST will come out that will restore the DI sound to a full acoustic miced up sound. There are a few hardware things that attempt to do it now with varying degrees of success I believe.
