Thanks, Takashi for explaining, it looks good to me as this is much closure to swift in terms of deps and use case. 
I am ok with keeping py2 support but I think saying py2 is supported without testing, is very confusing and risky. 
Instead of breaking users for untested-supported things, we should either test it or drop completely. 
In that case, can you also revert the patch dropping the py2 testing/requirements? which is this - https://review.opendev.org/#/c/692277/5

After that, I will propose adding the Storlets in python2-keeping-projects list in goal doc.
