They do use it for a lot, but there are a lot of things that need to authenticate to each other in a modern ecosystem, especially if you're trying to replace security based on network boundaries as trust boundaries with zero trust (as the government is).

I worked with more than a few IL4 systems where the PKI/smartcard stuff was simply shoved into an F5 that did TLS termination and then everything on the internal VPC just used HTTP headers without even a crypto signature to convey which user had actually logged in.

As with anything else, the more you make it easy to the do the right thing, the more often you tend to see the right thing being done. So agencies that make it easy to request server PKI certs see increased uptake, other agencies just have server-to-server auth done by PSKs / API keys instead.

So the concern isn't usually cost but compliance, if it's nearly impossible to get those little developer experience affordances ATO'd themselves, agencies will instead just focus on getting the mission system itself ATO'd come hell or high water and the devs just get told to piece it together however...
