Personally I've been considering, based on the fact that it's apparently fine for full casters to have fiat/always work-type abilities, giving Rogues a sort of "auto-succeed" ability like once per long rest (probably going up to 3 times by L20). I.e. "After you fail a skill check with a skill you have Expertise with, which you were capable of succeeding at, you can declare that you succeeded at it. This is treated as a normal success. You may use this ability once per long rest".
Obviously this would only work for DMs who understand that succeeding at Persuade on the king doesn't mean he automatically gives you his entire kingdom, but at this point I think that's like 90% of DMs (I also think this existing would help the remaining 10% to understand that a successful Persuade check is not mind control).
