Assuming libmagic >= 5.39, the following features can be dropped (see #16):

• v5-04
• v5-05
• v5-10
• v5-13
• v5-20
• v5-21
• v5-22
• v5-23
• v5-25
• v5-27
• v5-32
• v5-35
• v5-38

Iirc the API didn't change in .39, so v5-40 is the first one to keep.
Looking at the supported versions, the lower bound is .38, so default feature wouldn't change.
