When I removed unused code outright some people complained that they 
plan to use it tomorrow or in the next millenium or whenever.

When I #if 0 it other people complain that I should remove it outright.

So whatever I do, there's always someone complaining.  ;-)

In this case the code looks as if it might get used at some point in the 
future.

But if a maintainer tells me to resend a patch with the code removed 
instead of #if 0'ed I'm always glad to do this.
