depended on this being true.

d1f754c02e Allow requirements to record tags
To allow

  depends_on :x11 => :optional

and friends to work as expected, make requirements record any tags and
add special handling to the X11Dependency to record both a minimum
version and additional tags.

bbfb6400c7 Manage Requirements using ComparableSet
ComparableSet only allows a single object of a given class,
choosing the object with the greatest value. This was mainly created
for Requirements, so that, e.g., two X11Dependencies of differing
strictness don't both end up in the same requirement set.

Fixes Homebrew/homebrew#15240.
