Personally I think it is always advisable to use "${var:?}".

Put this case:

STEAMROT=$HOME/.local/share/Steam
rm -rf "$STEAMROOT/"*

In this example there is a missing letter in the variable declaration, and this cause the second commands to wipe all your files.

There's definitely a case to be made for safe habits. SC2086 has a corresponding optional/"strict" check, SC2248. Potentially, an optional version of this check could be useful, as well? I do think it would be nice to take advantage of the extra information by default.

In the end, I certainly don't feel that the current behavior is bad, simply that it could perhaps be refined. This issue is really just the result of having been surprised by SC2115's behavior compared to SC2086. 🙂

As for the typo, that would still trigger SC2034 for the unused variable and SC2153 for the undefined variable, both of which I feel are more relevant to having made a typo than not knowing whether the misspelled variable is empty.
