thanks for the reply. i think it could be nice with low carbonation?
I had a dubbel on cask once and while a fine beer the lower carbonation also minimizes the brightness of the yeast character. It was more brown ale than dubbel. 1.9 vol wouldn't be quite as flattening as cask but Belgian abbey/trappist styles are usually closer to 3 than 2. I know some people find high amounts of carbonation unpleasant to drink and if you don't enjoy it then you shouldn't brew to satisfy anybody else.
