Frontage is province-specific.
Frontage is the same in every province, isn't it? They have specifically said that the rational is that even in large-area provinces, there are only so many places that units can "fit". ...?
The solution you're looking for is detaching parts of divisions to fill out the less active sections of the front.

Do you mean detach divions to fill? Brigades or 1-brigade Divisions are uncommandable, so loose all command bonuses. Why would you put a tiny, non-bonused unit on an active front? To use the MMORPG term, it would be an agro-magnet.
What I'm actually looking for is the real frontage number, and whether or not the frontage will be measured across the whole front, or each province individually.
I have to confess I'm nervous about this rumour that the province frontage is 10. I feel thats a huge frontage number and will end up encouraging the scourge of "Giagantic Mega Armies" or GMA for short. If you consider that an army with good commanders will use three or four times the number of divisions necessary to cover a frontage, as the Corp commanders will by cycling those divisions during battles, and each division will have a frontage of between 2 and 6, then an army covering an 8 province-front could concievably utilize up to 120 divisions for a single phase of a campaign!
If the province frontage is not contiguous, then at least there won't be overspill for formations that exceed the provincial frontage. This would curtail the GMA condition by making excess redundant. Inversely, within a single region, its not realistic that a formation in a single province would be restricted to attacking across only its own front.
I'm still trying to visualize pincer movements, and getting very confused. I have a hard time seeing how anything other than 3 or 4 times the number of historic divisons will be able to do this.
