I started playing bass in the late 90s when slap and pop and/or slap + strum were both very popular.
Primus was, technically speaking, a pop band at the time. RHCP was everywhere. Incubus still had Dirk/Alex. Korn was big. etc, etc.
So, as a "child" of that era, I went pretty far down the slap rabbit hole. More or less learned everything Primus did through 2001 or so.
I've really only used those chops, in the intervening 20ish years, in original bands. Even in those cases it was only an option in bands where it made sense musically. e.g. drums, bass, guitar, vocal things.
If you add in keys, or a second guitar, it's really hard to do any sort of advanced slapping or strumming, while keeping roles and sonic space sorted out. My personal take is that Les Claypool, for example, would never have gotten away with being Les, if he didn't write the songs, if he didn't sing the songs, or if Primus had a 4th instrument.
In the highest caliber music situations I've played in (e.g. gigs and jams with people much better than me) slap is usually considered kind of a joke technique. Their attitude is more of "oh that's a thing wankers do at NAMM".
So, no. Outside of a very basic ability, you'll rarely use those chops. Unless you're in a Primus cover band, or are working on originals where it's needed.
