Code Review
This pull request successfully replaces all usages of the custom impeller::SPrintF function with the standard std::format, and removes the SPrintF implementation. This is a great improvement for safety, readability, and maintainability. The changes are mostly correct and well-executed. I have one minor suggestion for improving consistency.

There was a problem hiding this comment.
std::format can handle std::string_view directly, so calling .data() on label and trailing is unnecessary. You can pass them directly to std::format for cleaner, more idiomatic C++20 code. This also applies to a few other locations in this PR.1
Suggested change
| reactor_->SetDebugLabel( | |
| handle_, std::format("{} {}", label.data(), trailing.data())); | |
| reactor_->SetDebugLabel( | |
| handle_, std::format("{} {}", label, trailing)); |

Footnotes
-
Following the Google C++ Style Guide includes using APIs idiomatically.
std::formatis designed to work withstd::stringandstd::string_viewdirectly, so calling.data()is unnecessary and less clear. ↩

We have std::format at home. This is superior for a few reasons. The caller doesn't have to remember the format string for the type. I believe std::string_views that are not null terminated are also handled correctly. Also, we don't have to maintain and test our own SPrintF.
