I get that this function will no longer be necessary in 8.3, but the documentation actually says that it has been _removed_, suggesting that any use of it will break scripts. Surely that can't be the case. Please tell me that it's only deprecated, not gone entirely...

> This function converts from a normal DataSet to a PyDataSet, which is a wrapper class which makes working with datasets more Python-esque.

Just deprecated/hidden, that's a documentation mistake.

I have customers that are using that function. Do I need to make them convert to the utilizing the dataset methods as part of 8.3 conversions to help future proof things?

> Deprecated `system.dataset.toPyDataSet` and the entire concept of manually wrapping datasets as "PyDatasets". Instead, all datasets will transparently be exposed to scripting as if they were PyDatasets, in a backwards compatible manner.

The above is from the change notes for 8.3.  
In theory you can just ignore the change completely, but legacy code will also work fine for now.
