In both of those cases, the quotes are optional.  Add them if you wish.

In variants that use the test or [ commands, the quotes would be
required.  (Note that test and [ don't permit glob-style pattern matching,
so any such solutions would require something like "${3,}" or "${3^}" to
work at all.)
