Expressions $EXP not working in include conditions

Is it just me, or do $EXP visibility expressions not work inside includes? Seems like a bug to me.

e.g.

Code:
<include condition="$EXP[myvisibilityexpression">myinclude</include>

If I can’t use them for includes they aren’t a whole lot of use because I still have to maintain separate conditions for my includes and it actually makes my code more difficult to manage because I have to remember to update both conditions and the expressions rather than just do a batch find and replace.
