Hi @robvp, you’re not the first to consider this. 
You may be interested in the following post (and the whole thread).
The result of the above was a couple of components which might not quite do what you want, but can go a step to reducing “row splitter chain hell”!
Both of these components work on the basis of the value of a “partition column”. So if you already have a column in your table that you are splitting by, you can use that. If not, you could create the partition column using a rule engine or other node and then follow it with one of the components:
Each produces a fixed set of outputs. Unfortunately there’s no option for dynamically adding outputs on components, but you can chain the last output to a further splitter if you need more than 10… still chaining but greatly reduced over the regular two!
The first one auto-partitions based on the column, using the values found. The second gives more control by allowing a regex pattern per output.
(I cannot vouch for performance though, as internally they also chain a series of row-splitters)
