Emphasis mine: "only"?

"Just add some command line switches" is not exactly a nice solution. From
personal experience, the vast majority of java users do not know how to add
configure command line switches to the various compile and build VMs being
started by their build tools of choice, for example. Also, not something
Alan mentioned here: Adding the command line switches is currently the
_ONLY_ solution, so tools that are aware of the issue can't even fix it,
other than by mangling modules (bad idea, I think we all agree on that I
assume), or advising the userbase not to actually USE any of the modularity
features and, preferably, to avoid switching to JDK9 altogether.

Emphasis mine: "starting out"?

This gets back to an earlier issue I raised on this mailing list: Okay,
starting out this isn't an issue, but by having no way to opt out of
export-based access control, it's a bit like switching from driving on the
left side of the road to the right: Unless the entire greater java
community switches in the same instant, we're all going to have a bad time.
A way to opt out needs to exist, and the fact that the discussion is still
going, and no plans have even been stated yet, means in my opinion that
jigsaw is not fully baked yet.
