It's very frequent in scripts to enable set flags to avoid common pitfalls and make them more robust and safer:
#!/bin/sh
set -Cefu
# ...
At explainshell it can be clearly seen at a glance what each of these flags do:
Of these, -C doesn't exist in fish, and -e, -f, -u all have different meanings.
It'd be cool to filter them out from the output entirely.
My only concern would be set -- x y z constructs, that set elements to the builtin pseudo-array.
