all the other examples require tools, special handling (you cannot touch the gold edges or pins),
That it is hardly true these days. Inputs are protected with 2kV ESD diodes for some time now - ever since days of the A series CMOS was learned and the B series came out (decades ago).
But it is still possible to get unprotected devices that operate at high frequency such as GaAs MOSFETs used for RF because the protection would slow it down too much.
(ESD precaution continues to be recommended for products with exposed pins because it is not 100% possible to be sure what the ESD is doing in every combination of circuit design. The strength of ESD discharge can be very different between different buildings. I remember in one tiled factory space, the discharge to any earthed equipment could send one flying.)
