Better analogy: you're paying 30% to apple, and over 50% in bad payday loans, and you're worried about the 3% visa/stripe overhead ... that's kinda crazy. But that's where we are in computer performance, there's 10x, 100x, and even greater inefficiencies everywhere, 1% for better backtraces is nothing.
Absolutely. We've gotten numerous double digit performance improvements across applications, libraries, and system daemons because of frame-pointers in Fedora (and that's just from me).
