As for why they have not improved the design... There is not much room for improvement.
The design considerations are as follows.
We want to make sure NO gas flows if the pilot is not lit.
Thus you have a thermocouple (Electric type) that generates about 1/2 volt and at a few ma when heated.. You have an electro-magnetic valve in the T-Stat that senses that current.. The current is NOT enough to open the valve (Again a safety feature) so you do that USUALLY by pressing down on the knob.
NOTE: that often the knob MUST be in the PILOT position in order to press it.
Light the pilot, hold the knob for ONE FULL MINUTE to allow the pilot to heat the Thermocouple and generate enough current to HOLD the valve open, then release and turn to set temp. Main burner should then light.
I have found that I need to hold the lighter on the pilot and thermocouple for a while to help heat it up.
