Has Qualcomm ever engaged in significant semi-custom work? (no, adjusting dvfs for a special "for galaxy" SKU or adding pluton to 8cX gen 3 doesn't count). Samsung was a semi-custom partner for Apple in the early days of the iPhone (to the extent that the M1 still has some Samsung IP in it[0]).

I heavily doubt that Qualcomm is even capable of working in such a role. In fact, the C-suite probably believes that their core competency is lawsuits and not modems, anyway.

(Edit: I meant semi-custom SoC design/architecture not cores, like https://www.anandtech.com/show/7281/understanding-amd-semi-c... )
