Technically, disabling would be possible but you lose some important
benefits such as when enabled, cleaning a package will remove whatever
it put into staging.

One of our problems in OE is too many code paths. I'd like to see us try
and minimise that problem. Disk space is cheap and this code shouldn't
take much more time.

Once combined with checksums, it should actually save people large
amounts of time as needing to rebuild from scratch should be a think of
the patch (unless you make a change effecting everything in which case
you'd expect it).

Cheers,
