I can ensure you that it is much better than what you suggesting.
Anyway there are plenty of ways to have additional data (static arrays,
persistent variables via osaka plugin, artificial tickers, external database via ODBC connectivity
so everyone can choose whatever he/she prefers). There is zero reason to
add bloat to the software just for one or two users.
External connectivity is provided for anyone who needs more, while keeping
baseline product well in bounds.
Best regards,
