Isn't the dividing line between the largest possible gas giants and the smallest brown dwarfs a bit fuzzy?

The definition of a brown dwarf is that there is enough heat and compression for deuterium and/or lithium fusion, but not protium fusion.
The exact model limit is unclear, but the physics modelling is relatively straightforward.
