Actually it's not. If you review the original FR from that thread, I wanted to be able to set up all patterns and their attributes at once (name, number of rows, the pattern's "time signature" <I>all at once, with as few clicks as possible</I>.
Your solution answers THE original request, and it's a good start for mass creation of patterns, but I for one prefer a database way of entry. If you never get to it, that's fine; hopefully a future dev might find it beneficial...
