I can not list all the issues.
Con Some knowledge of programming required
Hammerspoon is scripted in the Lua programming language, and some familiarity with programming in general will be needed to use it. Some plugins exist that can be used by adding some files to a specific folder, but this will not give the flexibility that is so key to Hammerspoon
Con No Longer Maintained
Bare Bones, the developers of TextWranger, recently ended maintenance and support for the product. Per the Bare Bones website (https://www.barebones.com/products/textwrangler/): "We have sunsetted TextWrangler, and we encourage anyone interested in TextWrangler to download and use BBEdit instead."
Con Not Compatible with macOS High Sierra (10.13+)
Per the Bare Bones website (https://www.barebones.com/support/new-os.html): "TextWrangler is not compatible with High Sierra. We suggest that you use BBEdit as an alternative . . . ." Since Bare Bones officially sunsetted the product, it will unlikely be compatible with subsequent macOS release versions either.
