Don't know. But here is the idea: drop table rollback is needed in
automation of DB restructuring. There is no need of that in web or
'custom' applications for that feature. It is only needed in complex,
two-stage applications, when first stage manages the underlying DB
structure for the second. In other words, in big projects. If you
are not very ambitious, you can get rid of that complication. I
personally can live without it, though with some redesign of my
project, and there will be no restructuring 'on the fly'.

Sadly I always supposed that rollback can work wonders and resurrect
a table killed in transaction. I was so sure it was so that no testing
had been done. It isn't mentioned in docs.
