This should have similar impact of declaring new records (minimal), and in addition, this doesn't introduce new classes, so there will be even less of an effect.

Yes, but the comparison should be against the non-allocating (current implementation) not the initial implementation in the PR. Startup measurement are done periodically and if there is any impact it will show up.
