I'm curious what you do and don't teach at different ages.
Just to add to the mix, here's a list of the MMA technique fouls from the Nevada State Commission. You're not supposed to do these in an MMA match:
Below is the list from the banned techniques you mentioned and my comments about whether or not I was taught them/taught them myself. I learned all of them by the time I was a 6th gup, IIRC. Likewise, I taught them all to my students when I had my own club.
Butting with the head (both with the forehead and the back of the head though these techniques were presented as last resorts due to the possibility of being injured yourself)
Eye gouging of any kind (using flat finger tip thrusts, cross cuts, fore- and double finger strikes, thumb strikes)
Biting (no)
Hair pulling (yes, to escape from being grabbed)
Fish hooking (no)
Groin attacks of any kind (uh, yeah,
tons of these, literally too many to list)
Putting a finger into any orifice or into any cut or laceration on an opponent. (no)
Small joint manipulation (yes)
Striking to the spine or the back of the head (yes, with both kicks and hand techniques)
Striking downward using the point of the elbow (yes)
Throat strikes of any kind, including, without limitation, grabbing the trachea (yes, many such techniques)
Clawing, pinching or twisting the flesh (yes, especially helpful when being grabbed)
Grabbing the clavicle (no, but we learned early on to just break the clavicle with the base-of-knife-hand)
Kicking the head of a grounded opponent (yes)
Kneeing the head of a grounded opponent (actually no)
Stomping a grounded opponent (yes, the stomping kick with the back sole is a pretty common technique)
Kicking to the kidney with the heel (yep)
Spiking an opponent to the canvas on his head or neck (no)
Holding the shorts or gloves of an opponent (not holding their shorts or gloves, but being taught to grab the opponent and hit him several times definitely)
Spitting at an opponent (no)
What do you reserve for adults or select groups? Are there some things you just won't teach at all?

Most of those techniques are taught to students teenage and up but some come into play younger. All the ones indicated are taught to adults. Frankly, I'm surprised people would omit some of the techniques listed. Others (such as biting and spitting) I'm not surprised at.
