B2B seems like the obvious standard of comparison here. Customer support really can be worth millions there, and that's reflected by how the system works.
Keeping customers happy as a general principle isn't gendered, or undervalued, or much of anything else. It just varies from "you're an essential customer, you can call our engineers night and day" to "abandon us forever, see if we care". Any kind of generalization like "treated as women's work" or "don't put technical people in front" is going to find counterexamples in big, high-stakes contracts.
I saw one contract with a clause that a Sev1 incident had a 15 minute SLA to the highest tier support engineer and 30 minute SLA for initial contact from an SVP level exec to the customer CIO.
And in that vein, I've worked with some very skilled receptionists. But they're not doctors.
