I don't think, those cases are rare.
Imagine a custom suffix you want to set to an empty string in your 
flexform. Or a float field to enter the tax amount. There is no way to 
distinguish between 0.00 and NULL.
It would be a neat feature to enable optional flex form fields that you 
could remove resulting in a NULL (or not set) value.

For extbase we went the safe way for now: If a flexform field exists, it 
overrides the corresponding TS setup no matter what.
If you have a better idea shoot, but "($flexFormValue !== '') { 
$settings[$key] = $flexFormValue)" is not an option for the reason above..
