I could narrow this down to an environment containing only Infiltrator and NonlinearSolve.

If you call precompile in such an environment, both Julia 1.13.0-beta2 and 1.14.0-DEV.1817 precompile NonlinearSolve again and again with every precompile call.
Julia 1.12.5 behaves correctly and does not recompile the already precompiled package.

I haven't checked whether the packages do anything undesired.

• If so, I want to get a warning about this so that I can report it to the package repositories.
• If not, this looks like a regression.

Either way, I currently think there is something to do before 1.13 is released.
