Maintenance is not a “problem” even if I am the maintainer or in my case, the “rearchiterer”. It’s what they are paying me to do. What a company needs at one phase of its existence is different than at another phase.

It would be just as wrong for me to come into a company at the beginning of its existence when they are just trying to go from 0 to MVP and worry about unit tests, branching strategy, and “process” as it would be to promote the pioneer to a team lead.
