Jigsaw removes the ability for tools to help name transition
Robert and I wrote a bit previously  about the issues with the
automodules in jigsaw (hint: they use only the filename to default a module
which we've demonstrated is a terrible idea). There was a happy medium
which would have allowed library developers to select a name before full
modularization. Unfortunately, this has again been removed from the working
spec, and the vote is just around the corner.
I replied with the concerns and vision  but it has since been
unanswered. We need more people to speak up on this issue.
Several other EC members worked together to share concerns and this is a
scary read , along with another discussion of module names here
