One thing I’m wondering is how this package’s license (GNU LGPL v3) will work with other packages which desire to depend on it. I’m not going to bash your choice of license; I’m a fan of the GPL/LGPL/AGPL license family in general. Is the license that you’ve chosen intended to signify intent for how this package should be used?
P.S. This package looks awesome, and regardless of the license or registry situation, I look forward to giving it a spin!
