> the V2 position exists in any sentence,
dependent or independent, V1 exists only in independent sentences.
How would you cope with the perfectly good German sentences:
Gegessen habe ich schon.
Schlafen will ich jetzt, lesen nicht.
The one invariable rule is main verb second. The idea that the last
position must be verbal is a distortion of the evidence - in my opinion. It
is too easy to find counter-examples.
For example, all simple declarative sentences will break your rule - whereas
my suggestion of SVO is maintained invariably in all declarative sentences
of whatever complexity, without exception.
