Splitting engineering teams into defense and offense

It feels like having 50% of your team's time be spent on urgent support, triage and bugs is a lot. That seems like a much better thing to solve versus trying to work around the issue by splitting the team. Probably having those people fix bugs while a 4 week re-factor in a secluded branch is constantly in process doesn't help with efficiency or bug rate.

It's a team of 4, so the only options are 25% and 50%.

But the fact that this explicit split makes the choice visible is clearly an upside.
