DFN tablature is designed for the professional guitarist who mainly plays 12edo guitar, but is sometimes hired to play microtonal music on a guitar they don't own. They would generally prefer tablature over score. DFN tab would be much easier for them to read than tab with conventional fret numbering. Upon seeing e.g. "6a" or "7", their muscle memory will place them in the general vicinity of the proper fret. Markings on the side of the guitar neck can group the frets into categories, making the tablature even easier to read. Possibly fretwire of two different colors could be used, to make the grouping even more obvious.

Using "h" to name frets causes the grouping markings on the side of the neck to be asymmetrical, in the sense that the upper half-octave is not a mirror image of the lower half-octave. One solution is to rename e.g. 19edo's 9h as h10. Mnemonic: 9h means "nine plus a half", and h10 means "halfway to ten". Another solution is to not use "h" at all. If taking this approach, care must be taken to never use 9h or 9.5 in tab for a 19edo guitar marked this way.
