Onboarding Friction for WTI/Brent Futures Accounts

Curious to hear about others' recent experiences opening accounts for WTI and Brent futures. Specifically, has anyone encountered significant hurdles with KYB/onboarding processes at new brokers or even existing ones when trying to add these instruments? I've been with a couple of larger names for years, primarily equities and FX, but adding crude futures has been surprisingly clunky. The documentation requests feel disproportionate compared to the initial leverage on offer, and the turnaround times for approval have been much longer than expected. It almost feels like a deliberate friction point to manage client numbers or risk, rather than a genuine compliance bottleneck. Any insights on this, or recommendations for brokers with a smoother, more efficient path for energy derivatives?
