Wait just a moment. Libreoffice had python for years, but nobody cared and instead complained about needing 100% compatible VBA for "real work". Where are those people now?
The reason we're doing this is to make money, and nobody wants to buy Excel spreadsheets that don't run in Excel.
If people don't know about it, people won't use it.
If people are accustomed to something different, people will ask for it.

By having Python in Basic, it becomes available to cells too, since Basic macros are callable from cells.
Note that you may need to reduce the security level to 'medium' in the drop down Tools->Options->Libre Office->Security->Macro Security. When LibreOffice opens, it will ask you whether you want to enable macros or not.
