late surrender rules

Late surrender seems like it barely gets discussed compared to other blackjack rules, but it honestly changes things quite a bit, especially for risk management. I know the house edge drops a little if you use it optimally, but the problem is so many tables either don't offer it or have some weird "no ace showing" restriction.

I keep running into debates on whether it's actually worth seeking out late surrender tables, or if the effort's just not justified by the numbers unless you're going really high stakes. Curious what everyone thinks about the long-term value here, especially when you factor in online vs. in-person play and stuff like session volatility.
