Even "touch" as a sense makes no sense. Feeling pressure and feeling heat exchange are completely different senses. In addition to that there's obviously a kind of pain felt by the skin that is neither extreme pressure nor a temperature extreme but an indicator of skin damage.

Then there's proprioception as mentioned in the article, the sense of balance/acceleration as measured in our ears, and together with smell, sound, taste and sight we are already at 9 senses.

And as you mention many of the things we actually perceive are derived from many senses. The "taste" of a steak is a mix of smell and taste, your balance is a mix of sight and your acceleration, temperature is something we can't actually fell but can derive from how much heat enters or leaves our body, "pain" is a giant category spanning nearly all senses, etc.
