Great contributions on your side. I think having a 1:1 call wrapper is necessary to have a low-level API available for different use cases but I wished we could all build new high level APIs on top of that one single well maintained code.
Even so, it's a great effort on your side and maybe it's better to use a well tested code like yours for new apps. I find it a little risky for new devs to join since most of the sample codes are for steem-js and it makes your job much harder to promote your solution.
