Surprisingly development is very even this way, a check with a desitometer proves it.
The downside is you're restricted to a length of film you can hold outstretched arm to arm. Really helps being 6 foot + if you want to handle a decent length.
There are a lot of alternatives, spool to spool aerial processors work.
