I'm guessing you don't work in a company that designs or builds laptops :-)
b/c they agonize over parts like this. I ran into one situation where the
ODM removed a single pulldown to save cost. One little
almost-too-small-to-see part which cost a fraction of a cent. But a laptop
BOM is a consequence of thousands of decisions of this type.

Nope, the switch is definitely a non-starter, esp. given that there are
solutions that don't require it.

It's not just the part. A single simple part like that has all kinds of
follow-on effects that are not obvious unless you've been at a company
which designs and builds consumer electronics.
