Some pedals like Blackout Effectors have so many different knobs. The variety of combinations allow users to use it in so many creative way, but it could potentially make it complicated to use. Most pedals only have two or three knobs, focosing on several effects, making themsevles easy to use.
I would say large companies are making pedals for more general uses. Users are the general public. The effects are just more standadized. However, smaller companies are making pedals that are more stylish and special. It’s just interesting to check out these creative pedals.
The Electro-Harmonix 8-Step Program Analog Expression Sequencer Guitar Effects Pedal has a step sequencer that without a gradual movement. You basically have to “program” certain steps, and these steps can be repeated in a loop.

SP5T means a single-pole 5-throw switch.
A Momentary switch remains in its “on” (or “off”) state only as long as it is being compressed. It can be used for products that are dangerous to be left on like hair driers. A latching switch needs to be pressed once for ON and again for OFF, for example a light switch.
