How do you estimate "Free" here? Sorry I didn't check the source code in git,
but from the "Details" below nothing leads me to believe that this FS is
doomed to only be able to usefully utilize only ~86GB of the partition, and not
more.

Are you ready to answer the flood of questions from people why their disk is
only 62% efficient, and how to tune it to 100%? :-)

Why use underscores instead of spaces?
