That's fair. Without testing, I cannot truly be sure what appropriate "fixes" would be for how punitive Exhaustion is. My stab there was, in effect, trying to address the "you can't fix it" problem without making Exhaustion yet another slap-on-the-wrist penalty because of it being infinitely removable. Having such an extremely serious, death-spiral-prone penalty be essentially impossible to manage, other than resting (possibly for several days at a time), is part of why it's SO problematic. Granting a way to partially mitigate it, without granting absolute "you can just wish it away after every encounter" control, seemed the best quick-fix way to deal with it. But testing is always required before you can say with confidence that any adjustment does what it's supposed to do.
