el-Latn is more vague than el-Latn-[variant], which in turn is more vague
than el-Latn-[variant]-[subvariant], and so on. Variants and subvariants
must be registered before use. Often vague tags are good enough: the price of
infinite precision is infinite verbosity.

It specifies a particular (subnational) region, a particular
orthographic variant, a particular time period, a particular dialect
or sociolect, etc. etc. It is used when the basic RFC 3066bis tag of
language-script-country (where "country" also includes supranational
regions) is insufficiently specific.
In the case of el, a country code is probably not useful.

Formally speaking, no. In practice, probably also "no" in this case,
because there are so many formal and informal ways of writing Greek in the
Latin script, with none particularly dominant.

If I have seen farther than others, it is because I am surrounded by dwarves.
