I think that it's a problem of "outsource" vs "in-house." Government is like a microservice architecture where each service being built by a different corporation with a non-technical PM leading integrations. Then, it gets maintained by basically nobody and is expected to work in perpetuity.

From what I have observed, having an in-house technical team at the government - even small - aids all of these projects.

In fact, that's basically what this team is - SREs - professionals at running and maintaining code. A small integrations / uptime team that understands the implications of design decisions aids everything.
