That's a week or two of work (BCC is kinda creeky) and a whole lot of future customer support headaches to do that test (+), and the future revenues of BCC are the least important thing for my business success. I'd much rather spend the time on e.g. marketing AR and trying to 10x it's current revenue, or just do a week of consulting.
+ Despite having a totally consistent policy on this for the last five years, I have customers who either a) can't read and understand that BCC is a one-off purchase or b) actually think that BCC is billing them monthly (for free trial accounts) and want to cancel them to stop the billings on their Googles.
