@m-kuhn, it looks like this was being built by default. Why the change to a feature?

[m-kuhn]

It's crashing for me (with an osx-dynamic triplet) on load in specific scenarios and I don't require it there, so I prefer to disable this plugin. I can also make it a default feature to avoid a change in behavior for existing users

@AugP, @ras0219-msft, @vicroms, @BillyONeal, and I discussed this today.

@ras0219-msft - "If its broken for osx-dynamic, why not disable it entirely for osx-dynamic? At the very least, if there is an issue then there should be a report to upstream."

[m-kuhn]

@JavierMatosD It is possible that there is a conflict with other plugins / other components in my build and that in other scenarios softstore works as expected. That's why I preferred to make it a feature instead.
If you prefer me to globally disable it on osx-dynamic I can do that as well.
