If it doesn't support any of your users/co-workers then there's no need. But, there's nothing requiring the enforcement of the FHS in the linux kernel, so, generally, you can't take it's conformance for granted. If something works for X% of people and a trivial change makes it work for Y% of people (Y > X) then I advocate for making that trivial change.
