I think you are talking past each other (i.e. both of you are right,
in a way :)

There are many "dynamic" options, at least in effect, as far as I
understand Jorge.

Of course, the option's *value* itself is expressed as a literal
and is static, but it is "something dynamic", like a function (think
hooks), an expression, a shell command to be called or some form
of "implicit expression" written in a custom mini-language (think
`c-offset-alist'.

The job of interpreting the option as dynamic lies with the "receiver"
of the option, i.e. with the function(s) *using* that option.
Typically wrapped in some function.

Does that help?
