That's actually just `toOptionEnumSettingsSet('-f', error)`. I want to get rid
of the whole generated method by just placing the enum value in the
OptionDefinition struct (which requires some refactoring, but should be doable
in the long-term).

Agreed.

This seems like a lot of boilerplate when we have to write 300+ one-statement
methods for assigning options. Also I would prefer to not use tablegen for
generating executable code if possible because that is just hard to read (the
function we generate here is already something I only consider as a temporary
workaround).

If you mean if we can just call it `OptionEnumSet` instead of
`OptionEnumSettingsSet`, then I assume that could cause conflicts if we
implement multiple smaller commands in the same file (which we currently do).
