I'm old school--I try to give my customers what they want.

  That works when you have one or two customers per codebase. It's still not great. Context switching Python 2 and 3 is getting increasingly hard as 3 diverges. But when you have a few dozen customers on a single product, supporting edge-cases that require core forks becomes incredibly hard. Especially when you need modern Python features. We tried it. It doubled TTL for simple patches, and meant the Py2 version fell behind in terms of gross features. It was expensive for us, worse for the customer, so we dropped it and moved to a unified core. We had one customer threaten to leave but they didn't. Somebody in their IT department rubbed two brain cells together and agreed with our assessment. A customer might leave over this sort of behaviour, but again this worked out to be more cost effective, so we would probably do the same when Python 3 is EOL. Wheel keeps turning.
