Starts to make sense? I think you are making a lot of assumptions that non-technical people will understand any of this as opposed to simply opting for a completely turnkey black box solution.
nostr:npub1mhcr4j594hsrnen594d7700n2t03n8gdx83zhxzculk6sh9nhwlq7uc226 described an elegant solution to this: with cashu payment requests, the merchant itself specifies which mint the merchant is willing to accept.
At that point the wallet can do a swap between mints.
This actually makes accepting these things viable imo. If the merchant has a trust relation with a specific mint, and the ecash wallet has the ability to auto-swap, then it actually starts to make sense.

Discussion
I was saying it makes sense from a merchant perspective, assuming customer wallets can do these swaps automatically. I was trying to think of a situation where i would be willing to to accept these with low risk.
Yes the biggest problem is like you described, you actually have to think hard about the actual tradeoffs
Talking about merchant , what do you think of MCP square ?
