Almost all uses of String in xmonad are very short; if not, you're likely
doing something wrong. (The exception is the help text which does not need
to be optimal, and is simply output as is in what amounts to the most
optimal use case for lists. Meanwhile the overhead of Text is significant
for very short strings such as xmonad uses. Use of Text in this case is a
pessimization.

It would be on you to demonstrate that switching to Text is a net gain.
