Unfortunately, code written to a naive (wrong, but understandable!)
interpretation of the standard, though, will not benefit from this.
I think we "should" increase the alignment and make it constant again.
The backwards-compatibility hair would not be too hairy, really, because
the "dynamic" sizing could just return the same size as the static one,
if ever called.
