The JSON source generators are quite good, and a small performance boost worth considering even when not planning for AOT. The logging and RegEx source generators aren't even for AOT but for improving debugging tools [1] and performance.

Everyone should be exploring source generators already whether or not they expect to try out AOT.

[1] Debugging source generated RegExes is a dream, including being able to breakpoint inside a RegEx in the .g.cs file should you need to trying to get a tricky RegEx right. The code generated by the RegEx Source Generator is incredibly readable and includes great comments that explain what the RegEx does, step by step. Those comments show up as documentation comments on the partial .cs file side once the file is generated and can be used to double check that the RegEx you wrote matches what you expect it to do as you write/update the RegEx and the source gets regenerated (which happens pretty fast).
