You're correct. That of course requires 11-mins to cast
They need 4-8 hours for a long rest (4hrs for elves trancing) so 11 minutes is pretty irrelevant.
Not sure I've ever seen a party try to LTH for a rest while enemies have access to their location. I have seen an LTH used when being swarmed by shadows to cast heals & try short-resting to recover Channel Divinity. But a long-rest assumes the baddies have to be mindless/incorporeal and lacking in reinforcements.
Let's face it, you can take out a party cowering in a LTH by burying it and suffocating them all. 8 hours can move a lot of dirt.
