The fact that the tech architect spent any time at all contemplating this issue is a massive red flag to me.
Technical Architecture should be about making the right set of trade offs given the business goals of the system being developed. That involves spending a lot of time talking to people both inside and outside of dev team about what the goals are and how the decisions that devs are making are impacting everyone else in the company. That stuff is time consuming, but if there's any time left you should really be keeping up with the latest frameworks and tools.
If you're spending your time reviewing commits and enforcing coding standards, you're doing it wrong.
