I think it may be, but finer grained control is always nice as long as
1) it doesn't make things messy, and 2) it benefits the project as a
whole. I don't think it would make sense for the majority of situations,
but it may be a neat feature. It's for people who know a lot more than I
to decide...
I still have yet to check securelevel 2, tho - it may be exactly what I
need, or it may lack.
