Yeah, I've had all the same thoughts - and a few ideas about how to address them - but not been entirely satisfied with any of them yet.
Still thinking...

The new version of Clara, which has been completely rewritten (warning: very breaking changes), now has a dedicated Help() parser which, I believe, does what you want.
Also the new Clara uses a Result type for error propagation, rather than exceptions. Hopefully this is much closer to what you wanted (if you're still interested - obviously your original issue was raised a while ago)
