Bumping deps for no good reason is bad mkay? :)

On one hand @karenetheridge is right (except for the dzil is great part)
```
<ether> and yes, because keeping MinimumVersion means that if something else tries to add a 5.8 dependency, I'll see a release test fail
<ether> so keeping it is better than removing it
<ether> if I remove it entirely, I have to remember to do that check manually, and not having to remember to do manual steps is what makes dzil great
```

But so is @haarg:
`<haarg> you switched from the thing that works in all perl to the thing that doesn't work with old Exporter because of a bug in MinimumVersion?`

The solution is obvious - don't add moving parts where the code functionality does not require it, and keep *everyone* happy.
